Hi there.
Looonnnnnngggg time lurker here, but I found some things that I'd never seen before, so I thought I'd share with you guys. They're pretty messed up and look to be LSD induced Japanese-only games.
The first is PuLiRuLa (from what I can gather from the comments) where the character has to avoid a Alice in Wonderland inspired "legs coming out of a house" set piece.
And the second has a bunch of GTS themed bosses, which actually surprised me....but it's called Gokujyo Parodius Arcade and looks like a damn fun shooter.
