Enemies in Super Mario Galaxy 2
Some information taken from Prima Super Mario Galaxy 2 game guide.
Banzai Bills are large Bullet Bills that travel in a straight line continuously until they hit something. This type of Bullet Bill is unstoppable unless Mario has the power of a Rainbow Star.
Bats are only found in caves. They charge Mario and try to attack him. In order to defeat them, Mario must shoot the Bat with a Star Bit so that it is knocked to the ground. The bat can then be stomped or spun.
Bloopers are found only in the sea. They chase Mario and try to attck him. They can only defeated with a shell.
Bob-ombs are walking bombs. Whenever they see Mario, they begin the countdown to explode. Mario can, however, use this to his advantage by picking up the Bob-ombs and throwing them at glass cases or other enemies. Mario can also lead them around into glass cases to explode them.
Boos are ghosts that fly around. They can not be defeated, however, if you look the Boos in the eye, they will stop moving. If Mario spins, he can also put Boos behind him.
Boomerang Bros. are Koopa-like in appearance. Boomerang Bros. fire boomerangs at Mario. Boomerang Bros. take two hits to defeat and can be stunned temporarily with Star Bits.
Bullet Bills are very similar to Banzai Bills, however they are much smaller and can lock onto Mario once they see him. Bullet Bills can be destroyed by hitting walls or other enemies. Yoshi can lick up Bullet Bills and spit them out at glass cases.
Cheep Cheeps are found only in the sea. They will only cause damage if Mario gets too close to them. If Mario throws a shell at them, they can be defeated.
Chomp are large, round metal balls that roll around, usually on a set path. Chomps can be destroyed with a Rainbow Star or when they hit a bump or wall.
Choppahs are flying creatures that fly up and down in a continuous pattern. They cannot be defeated by Mario, however, Yoshi can lick them up.
Cluckbooms are flying chickens that drop bombs everywhere that they fly. Cluckbooms can be defeated by using Star Bits to stun them and then spinning them.
Hammer Bros. are basically the same thing as Boomerang Bros. except that they fire hammers at Mario instead of boomberangs. they take two hits to defeat.====Silver Chomp====
Silver Chomps are pretty much just Chomps, except that they are silver and they do not break when they run into things. Silver Chomps also do not follow a set path. Silver Chomps follow you around and try to run you off the planet. To defeat the Silver Chomps, you have to push them off of the planet
