Well, today I went to Hornet Hole, and since I don't consider it a minor glitch, I'll tell you here:
I went to grab Squitter and started to do random stuff. I killed all the spinies and the zinger above the ^ barrel. I turned back to the hook leading Squitter, and noticed you couldn't grab it if Squitter was near you. Blah blah. Then I thought, will it work back if I loose Squitter? Then I left Squitter under the hook and went to the next hook in the level, then I returned to the hook leading to Squitter and found me able to grab it again. Ok... mmm... Then I returned to the barrel and noticed a zinger was missing, the static one after the moving one. I found it strange and then I lost Diddy. I grabbed the DK Barrel and went to the left. I returned to the right near the barrel. But noticed another zinger was missing, I found it weird and returned to where the DK barrel was and found it again! I killed Dixie and went to it with Diddy, then I killed Diddy and went to it with Dixie, and it was there again!
I recorded a 3gp video with my mom's cellphone, but unfortunately, my cellphone is just recharging because is the only one that I can connect to the computer. If anybody has a video player that can play 3gp videos, like RealPlayer or Quicktime, I'll post the video in the next few hours
EDIT: 3gp is not allowed in the forums, I'll just upload it here:

Sorry for the hyper-mega-super bad quality. It was my mom's bad-recording-quality cellphone or nothing xD
