Just got Viewtiful Joe today in the mail, along with the bobblehead. Surprisingly the bobblehead wasn't plastic, but sort of ceramic, and was hand-painted. Anyway, this game is one of my favorites on GCN. The VFX powers are awesome and very well-used. In fact, I like the puzzles about as much as the core beat-em-up gameplay.
Pikkcuber: see the different colored tile on the ceiling? When the bomb is being thrown at you and is still in the air, kick/punch it up (you might have to use slow) and slow the explosion so it knocks out the tile.
