Vs. Mode is truly rife with this sort of weird glitchy stuff. It just keeps getting better the more you look at it.
Accomplishments include:
Seeing the amusing effects of putting two players in the exact same spot
Achieving great jump height
Roboy winning with no health remaining (no idea how that happened, since it's possible for both characters to die simultaneously)
Developing a method of closely examining a character's ass and thighs
Showing just how stupid the game's AI is, as it decides to jump like an idiot in the last clip and bugs out the victory screen
And although I accidentally cut it out of the video, I also managed to find out that two characters can pick up an item simultaneously (in this case, the health can on the edge of the water)
I should probably try this again later with four players instead of two to see what kind of havoc I can wreak.
