Okay, I haven't posted here in a long time, but here goes...
The shrinking slig glitch
does happen in the ps1 version, it's just rare. Like while in AO near the end of scrabainia, there is one floating mine and two sligs in the background. So I possesed one of the sligs. As soon as he was posessed, the other slig shot him, and he just shrunk. I was LMAO.
Also, I found this a couple of weeks ago. This isn't mine, but it's funny.
