I Don't know how,but I will give you this:Just keep shooting him until somthing
happens!?!?!?!?!?

okay first hit plankton with danny phantoms ghost beam then if you fell down just kill the
jellyfishes and find spongesbob bubble flyer then if you get it fly to the top then reapet
the processs until planKton will be upside down...........

planktons craby thing jumps in a pattern. he always returns to the doorway. get spongebob
to put bubble bombs all around the places that you know hes going to land. he will for
some reason eat the bombs. it takes a while to get the right timing so dont get
frustrated. when he flips over run up and hit him with your glove.

when i hit plankton he wont let me back up. I NEED HELP

Whoever put the killing Plankton answer is an *****.He put it for the wrong game system.

Thers no way to beat plankton because ****** thq messed up when they made this game.

plankton is unpside down and so big and fast i cant get back to the ledge to hit him more
what do i do
