Super Mario 64/Enemies

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

Pink Bob-Omb
These are not enemies, but instead will activate cannons when Mario speaks with them. (This is only available after King Bob-Omb is defeated.)

King Bob-Omb
A large Bob-Omb with a crown and mustache (King of Town, anyone?) who will battle Mario at the top of his mountain over a Power Star. He needs to be grabbed from the hind-quarters and thrown, but not off the platform.

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

Koopa Troopa
A bipedal turtle. Destroying him (with almost any attack) removes his shell and reveals an embarrassing pair of pink boxers. His shell, once removed, can be surfed upon like a skateboard. Destroying the Koopa earns you a blue coin, but if you leave him shell-less for a while, he'll respawn a new one.

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 in one spot. He's invincible, but can jumped upon to reach higher spots.

Pirahna Plant
A man-eating plant that is usually found sleeping, but becomes violent once awakened. Killing this little weed earns you a blue coin.

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
Two-snowballed statues who either hop across a bridge, or pop out of the ground and throw snowballs at you. There is no way to destroy them, and must be avoided. To pass one on a bridge, wait until he faces you, then run under him when he jumps. (Please do not attempt to jump over him!)

Boo
White, chubby ghosts. If you make eye contact, they will disappear. Be sure to attack them from behind, with almost any attack you can think of. Each ghost wields a blue coin, worth five regular ones. A larger form of Boo dubbed "Big Boo" is seen three times 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 three coins out of this guy.

Water-Skimmers
A spider capable of land and water terrain. He can be killed by basic attacks or being landed on. They will skim across the water and attempt to ram Mario, or walk around aimlessly on land. They yield three coins when destroyed.

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, masked creature with a cannon for a mouth. He will fire round bullets at you, but is easily killed on contact.

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 who wants to steal your hat just as bad as Klepto. If, indeed, your cap is stolen, simply punch the poor fellow and take your prize.
