Ok... Since Max isn't here to explain all, I will attempt:
1.
Kintos were a mountain-dwelling race that used their single toes on each foot to dig into the rock face to secure themselves. As they lived in such dangerous conditions, they feared little, but the one thing they hated was to have a roof over their heads.
Then came the Glukkons. They enslaved them, getting them to pull loads [on the mountains, I think], but worst of all, they housed them indoors. with a roof above them.
2.
This is a Mug. And early production pic of a Mug. It is generally thought that this was changed, and that the big triangular Meetles are the new Mugs. I think that this was a cooler sort of Mug, but there you go. One thing that it probably is not is some sort of queen, as it is is capable of walking. Our best educated guesses suggest that queens will either resemble the original creatures [which this doesn't] or be huge and bloated [which this isn't].
3.
This is Maggie. Notice the Magog Cartel Symbol above her head. This is more what we expect of Queens, so you'll understand why I do not think that picture 2. is a queen.
I hope I have managed to clear some things up for you there!
