I managed to rescue 457 muds in AE by using a trick that I have known for some time but only recently have tried putting into action. Heres how I did it:
When you get to the the end area (where the glukkons are) of the Slig Barraks, BoneWerkz or Feeco. Depot, possess the glukkon and play through the level like normal. When you get to the phone, say hi to it and then say "Do it!" Straight after you say "Do it" depossess the glukkon before the cut-scene with the slig appears. The cut-scene won't appear and you will go back to Abe, but gas won't come down and kill you or anything. Leave the Slig Barraks or BoneWerkz etc. and get back to the main lobby of FeeCo. Depot. The area you have just visited will still be unlocked, go back in and any mudokons that you have rescued or killed will be back there. You can use this trick as many times as you like and keep returning to the area to rescue (or kill) mudokons. I played through the slig barraks about four times and finished the game with 457 muds! When you finish, it just comes up with the message you get if you rescue all 300 muds...
