StuperStar

: Its weak point is its head, but to hurt its head (it'll move its head out of the way of any Pikmin), you have to attack its actual tail, which has a leaf on it. Throw Pikmin (preferably Purples) on the leaf. But remember to stay away from his arms. They'll lash out at the Pikmin. Enough damage to the leaf will cause it to be completely stunned, and his head will fall to the ground, and you can attack.

: This enemy is a frog, but it isn't part of the Wollywog group. It's still an amphibutor, but just not a Wollywog. This enemy resides in puddles of water, waiting for you and your Pikmin to approach it. Once you come by, It'll start sucking up and drying out the little puddle it's in. Now that the puddle is dry, you can pass without Blues, making this enemy actually useful, and killing it may actually be a bad thing (in fact, this enemy has to be encountered before getting Blues).
