Super Mario 64/Enemies

Bob-Omb
Walking bombs. Either get them to chase you, or pick them up from behind and throw them. Each weilds one coin, but be sure to keep safe distance until they explode.

Goomba
Walking mushrooms. Jumping on them, punching them, butt-slamming them; pretty much anything works. Each wields one coin upon destruction.

Koopa Troopa
A bipedal turtle. Punch him and steal his shell.

Chain Chomp
A living, angry ball-and-chain with a large set of chompers. He will pounce at you if you get too close, and CANNOT be killed. You can run around his post to get some coins. Butt-slamming his post frees him, and he rewards you with a star.

Whomp
A large, gray, angry piece of cement. He will attempt to flatten you with his face, which can squish you quite easily. Run through his legs when he jumps, then butt-slam his bandaged spot to win 6 or more coins.

Thwomp
A large, angry, blue block. Thwomp will crush the ground repeatedly, and is invincible, but can jumped upon to reach higher spots.

Eel
A large electric eel, who likes to shock anything he touches. He can be lured out of his hiding places (The ship or his cave) by swimming in front of him. In the level "Can the eel come out to play?" a star can be seen on the tip of his tail, which must be grabbed quickly before he reenters his cave. Attempting to destroy him will yield no results, and we advise strongly against it.

Snowmen
Some jump, others pop out of the ground and throw snowballs at you. Avoid them.

Boo
White, chubby ghosts. If you make eye contact, they will disappear. Be sure to attach them from behind, with almost any attack you can think of. Each ghost weilds a blue coin, worth five regular ones. A larger form of Boo dubbed "Big Boo" is seen thrice as the area's boss. Simply attack him like you would any other ghost.

Spider
A large cartoon-like spider, which resembles a four-legged marble. Pretty much any attack will get you three coins out of this guy.

Man-Eating Piano
A piano only found in Boo's Haunted House. (The bottom left door.) It is invincible, but upon luring it out of its resting spot, a red coin is revealed. Do NOT attempt to play any songs on him.

MIPS
A small yellow rabbit who appears in the flooded basement before Lethal Lava Land. Upon catching him, he will give you a star, as he is too late for tea to fight you for it. He can be caught multiple times, the easiest strategy being to chase him towards the Shifting Sand Land wall then diving after him. He only appears twice in the game: When you have 15 stars, and 50, so be sure to visit him each time for an easy-to-get star!

Sniffit
A flying mask that shoots at you. Jump kick them for coins.

Klepto
A large vulture. As his name implies, he likes to steal things, mainly Mario's cap. He also can be seen carrying a star in the first Shifting Sand Land. He tends to be invincible, so the best strategy is to hold on to your hat and stay away.

Ukkiki
A monkey version of Klepto. His job is to steal your cap, too.
