I knew a guy who would cover his ears and rock back and forth and cry if we played this. Not in a funny, ironic way, either. Dude had a big Straw Hat pirate flag on his wall.

One of the main characters is a dude who used train wreckage to turn himself into a cyborg, but he couldn't reach his own back so he's only a cyborg in the front. He has a freezer in his stomach for storing coke bottles which he uses as a power source. Also he never ever wears proper pants.

I'm taking this summary from another website:

"o fight the massive zombie Oz, Franky, Chopper, Usopp, Zoro, and Sanji "combine" (really just stand on each other) into a massive humanoid figure dubbed "Big Emperor". It didn't do anything besides add extra comedic value, because Robin refused to "dock in" as the left arm, claiming that it would be "too embarrassing"."
