What a letdown... Out of four parts, only one was an actual animation, and that one lacked any sound effects or voices, on top of being a continuation of the same damn joke.
Goldencat's part made me laugh for several reasons. The art style, the sheer wtf factor, and the hilariously unfitting music.
Adam Ant's part was probably the worst (sorry!) I mean seriously, it's just an annoying squeak and a tweened purple jelly bean walking back and forth.
Aea2's part made me laugh a bit too. Seems more like an image than an animation, but as a loop it works. Zimmer's head was drawn really well, and overall the quality seemed quite high, except for the wheels.
Decent, but not nearly as good as the first.
