I think what I'll do for the rest of these places is make reviews of each of the areas with the main glitches and tricks to be concerned about, so here we go again!
Buzzarton
Right at the start of the new loading screen, if you do a boombat jump onto one of the pillars next to the gate that you're close to, then you can climb onto the top of the roof of the portion of the bridge that you just got out of. From there, you can jump onto the top portion of this area, which can take you as far as an area close to Buzzarton's city and as far back as the start of the bridge that triggered the cutscene in the first place with an OoB zone at the end of it. If you use a boombat jump at the exit to the Grubb village, you can get into the area with a little support for the big, metallic platform ahead. Once in there, if you travel across the set of four logs near the first building of the village as well as some rope next to the logs, you can get on top of one of the buildings with an opening at the back of it. With that, you can shoot at as many Grubbs as you want and listen to their sayings. Speaking of which, if you keep listening to their sayings for a long-enough time, you should eventually hear one of them say "Steef dude" as if you're already a Steef in the other Grubb village! With the trick that I presented in my speedrun route, you can also just use a boombat jump on any other side of the bridge to get on top of it. With the use several boombats, you can get all of the bounties early except for Meagly McGraw (I believe that was his name) and Jo'Momma, who I'm really close to reaching but there's this one height that I just can't reach for some reason; I'll make a video of it later.
Mongo Valley
In the forest, get to the shack area and over to the broken stove a little ways ahead of it. With enough speed, run-jump on top of it, get as much distance as you can, and jump toward the little edge of rock that looks like you can stand on it with all the speed that you have. Once again, get as much speed as you can, run across the rock path that you can walk on, and jump towards the roof of the shack. If you are lucky, you can use a hesitation jump from the roof to get on top of it, and you can get even higher by using the black wires that you can actually walk on. As far as that glitch goes, I've gotten as high as the sniper's postion on that big orange barrel, but that's about the only thing interesting about that trick. Now, go to the beginning of the cave that takes you to New Yolk City, and there should be a pile of rocks that you can get on. Jump from rock to rock until you get to the top position that looks very close to the top of the entire cave. Get on the highest point of the rock and use a triple boombat jump, and if you do it precisely correct, you'll be able to get on top of the cave! From here, you can travel around the forest by easily getting on the top of the level from where you're at. Don't bother trying to enter New Yolk City from above the caves because there's another weird, big pixel-thing that makes it so that you have to activate the cutscene if you want to enter the city. Also, if you go backwards as far as you can, you'll see that behind the rocks of Buzzarton's cave is another OoB zone and nothing more! As for New Yolk City itself, there are several ways to use the gates to get you on top of the houses and into the OoB zone, but if you run fast enough in first-person and jump onto the closest box to Xplosives McGee's hideout and towards the gate, you should be able to get over the gate and into the OoB zone with enough speed and percision. There's also some interesting stuff that's within the OoB zone, which I'll show in a video in the future! From the OoB zone, or with the use of a boombat, you can get on top of the lowest roof of the Port Authority building. From there, if you go over to the left roof that's next to this low-positioned rock, it just looks so close to your reach but you can't get on it without the use of the triple mountain climbing boombat! If you use it correctly, you can go away from this rock and get on top of the tallest roof of the Port Authority building. Sadly, though, you can't get behind the door that leads to the other portion of Mongo Valley because the door's pixel-thing has to be activated by the Port Authority building's pixel-thing first, so if there's some way to get Stranger OoB within the Port Authority building, then it might be possible to skip Xplosives McGee altogether; I doubt that it could ever happen, though.
With the several uses of the boombat jump, you can easily get on top and OoB of most of Mongo Valley's bosses' areas with their low buildings and rock positions that are within the places! Also, if you work with the boombat jump and the rocks surrounding you within Mongo Valley's area with the river inside it, you can fight both Fatty McBoomBoom and Elbowz Freezly early as I'll show in another video! Another big glitch that I should mention in this game is the jesus hop, which basically involves this one-frame trick where you can press A when Stranger is about to fall into the water and it will make Stranger jump again, no matter what the case may be! Which means that if I could make a TAS of this game, I could simply just jesus hop past any currents that I normally get past with other means, but even with pause buffering, this trick is too hard to do in consecutive succession (I've only been able to double-jump twice in a row at max.) One last thing that I should mention: remember in segment 3-2 where I jumped past that boat to activate the cutscene for the battle to begin with the casteraider (or whatever his name is :\.) Well, if you try to talk to the Clukker on the boat, he won't say anything or have any money to give you, and if you try to enter the arena with the Casteraider to begin the fight without the cutscene, it'll only show him there and the battle will never end as long as you stay there. Also, if you go over to the area between a rock and a building to the right of Doc's office, you can jump onto it with enough speed, and, if you do it precisely enough, you can use a hesitation jump to get on the rock above the one that you were partially floating on! From there, you can get on Doc's building to get on the platform that the Casteraider is on, and if you shoot him with a Zappfly, you can quickly bounty him! (I think this even works for the real battle with him) The game will say that you caught a red crossing for $10, but the status screen will count him as an outlaw nailer; you can also get OoB and even swim in the ground in this place, which I'll show off in another video that I'll make in the future!

De-Pantsing
The only real concern at this portion of the game is that Stranger can get on top of the big platform after just escaping the Casteraider's shack with the use of the tip-toe speed jump; nothing too big here. I almost forgot to mention that there is a way to use the sides of the ramp going up to the second window that you break of the Clukkers' houses to get you OoB with good jumping and speed, but still there's not all that much here.
Grubb Village (Don't read beyond here if you want to stick with the speedrun)
Aside from the minor ways to get OoB with the use of several boombat jumps, you can skip going to the Wolvark Docks by using a single boombat jump to get on top of the first tall rock of the two that are near the two gates, jumping to the other rock, jumping to a rock to the left of the one you're on, and using two boombats or using a narrow jump to get on the posts of the first gate to jump over past the second gate (there's also a way to do this without boombats, which I'll probably make a video for that later, but it's so hard to do, that no one would really figure it out on their own without lots of patience.) At the last waterway with the current, you can use jesus hopping to get you past the current without the boat, but other than those two tricks, this place doesn't have that many tricks.
Last Legs
Other than a minor strategy to get OoB, which requires great difficulty to succeed in the first place, there's only one major trick that can be done here. You can skip Last Legs entirely by getting on one of the last and lowest pipes at the right end of the barrier that leads to Sekto's Dam, sliding into the taller pipe, jump onto the linear postion of the taller pipe closer to the invisible wall, going up to the top of that pipe, and jumping with as much speed as you can toward the invisible wall. If done correctly, you should get slightly over the invisible wall, which means that you can keep the regular boombats for later on. By the way, the upgraded boombats suck because they can only make you jump as high as your regular jump, so it's hardly as useful as the regular boombats can be!

Sekto's Dam
There's yet another difficult way to get OoB in the last room before the Gloktiki's room as well as a way to get on top of the elevator of the Gloktiki's room, but other than that, only the last room of the game has some interesting stuff that can be done in there with regular boombats! With standard boombat jumps, you can enter the arena without the Gloktiki's in it, get out of the arena while fighting the Gloktiki's or Sekto, get on top of Sekto's pedestal area with an invisible wall near it to help you out with the fight against the Gloktiki's, get OoB into the large interior outside of the main room that you fight in, jump out of an open window with the help of getting OoB with the help of the position of Sekto's pedestal's area, climb up the pipes next to the windows with boombat jumps to get you
pretty high in the room, clip through the first protective barrier that appears when you begin your fight with Sekto by charging forward right when the battle begins, and even clip through the corners at the very bottom of this area with constant charging! If you can just get rid of boombat jumping in this game, then most of these glitches can be avoided altogether if you just make the regular boombats make you jump as much as the upgraded boombats do!!
There we go!!! I'm finally done with this list with all of the main glitches that anyone should really care about!! I'll make videos of some of these tricks later, but I'm now done with all of the lists with all of the glitches and tricks that would affect the game all that much! I have all of the lists now for all to look at and admire; I am done, and I am finished!!!!
