Most of the time there are two ways of killing a creature; either throwing all of your Pikmin on it or by using the C-STICK to get them to swarm around it. For the jumping frogs, never throw Pikmin at them or they will all be flattened. When the frog lands, swarm it. If you have enough Pikmin, the frog won‘t be able to jump. For Bulborbs, get at least fifty Pikmin. Sneak around to the back of it and throw Pikmin at it quickly. It should not have enough time to turn around and eat any Pikmin. For the enemy that keeps re-planting Pikmin, grab as many Pikmin as possible and throw for awhile before he gets close. Run until he stops chasing and then start throwing again.
