Super Mario Bros. 3/Enemies

Goomba

 * The simplest enemy. Just stomp on it. Bigger versions appear later in the game.

Para Goomba

 * Has wings. Will become a regular Goomba after just one stomp. Red versions of the Para Goomba cannot fly for very long, whilst the normal colour will fly much higher and for a longer period of time, whilst dropping Micro Goomba.

Troopa

 * The same enemy from the original Super Mario Bros.; just stomp on it and it will be in a shell, where it can kill emenies and break bricks. Firing it, however, will kill it completely. Troopa with red shells will remain on platforms whilst the green shell koopas will drop off platforms. Like the Goomba there are bigger versions later in the game.

Para Troopa

 * Has wings and will become a regular Troopa after just one stomp. Firing it will kill it even if you don't stomp on it first.

Piranha Plant

 * A plant that usually comes out of Pipes, but can also come out of quicksand. Cannot be killed by stomping on. Bigger versions appear later in the game.

Boomerang Brother
The boomerang brother throw boomerangs. They usually appear in groups on a few levels and can throw up to two boomerangs one at a time. They also guard valuable items in treasure chests.

Podoboo

 * A fireball coming in and out of pits. Cannot be killed.

Rotodisc

 * A rotating circle. Cannot be killed except as Tanooki Mario.

Dry Bones

 * A skeleton turtle that can be killed temporarily by stomping on it, but will come back to life after a few seconds.

Boom Boom

 * The boss at the end of each fortress. Can be stomped on 3 times or killed with 5 fireballs or one hammer. It has two methods of attack. It either jumps much like Mario can or starts to fly in the mid screen area before it swoops down to attack.

Buzzy

 * A beetle-like enemy. It has a shell like a Troopa, but cannot be killed with fireballs.

Hammer Brother
Hammer Brothers are yellow versions of the boomerang brother. They throw hammers upwards and towards Mario. The hammers cannot be destroyed and they protect the Hammer brother from being stomped on to some degree.

Cannon ball

 * A diagonally-firing ball that can be killed only by stomping on.

Bullet Bill

 * A horizontally-firing bill that can be killed only by stomping on.

Micro Goomba

 * A Goomba disguised as a brick. It can move around. It cannot be killed with fireballs. It also can be dropped by a Para goomba and cling onto Mario to slow him down and reduce his jump height.

Fire Snake

 * A snake-like line made of fire. It cannot be killed with fireballs or jumped on, but it cannot resist a flick of the raccoon tail.

Thwomp

 * A block with an angry face. It can be killed only with hammers.

Boo Diddly

 * A ghost that follows you around. It can be killed only with hammers.

Chain Chomp

 * A chain with a chomping face. Often attaced to a block. These are very agile and cannot be defeated by standard methods.

Fire Brother

 * An enemy similar to hammer and boomerang brothers that spits fire out just like Fire Mario does.

Rocky Wrench

 * An enemy in airships that can be stomped on or fired. It throw small wrenches when it gets the chance to. These projectiles cannot be destroyed.

Blooper

 * A squid.

Cheep Cheep

 * A fish that is found in the water as well as flying. When it is flying, it can be stomped on.

Boss Bass

 * A big fish that will eat you.

Lakitu

 * A cloud with a small creature which appears to be a koopa with glasses. This foe remains in the sky often above Marios reach. It throws spinys down to attack Mario. If Lakitu is defeated sometimes a new Lakitu will arrive after to take over the previous lakitus job.

Spiny

 * An enemy with a pointed top. It cannot be killed by stomping on it but can be beat down by fire. These can annoy Mario when a Lakitue throws these little guys down.

Jelectro

 * A jellyfish that cannot move. It can be killed only with hammers.

Lava Lotus

 * A plant at the bottom of the water that can be killed only with hammers. It spews out small slow moving projectiles. Based on its name these projectles could be lava based.

Spike

 * A green enemy which has an unlimited amount of spiked balls in its mouth.

Stretch

 * A line with Boos riding on it. The Boos can be killed with hammers.

Bob-omb

 * An enemy that will make an explosion shortly after being killed. It can be thrown when it is stomped on.

Rocket Engine

 * A flame of fire that cannot be killed.

Sledge Brother

 * A giant version of the hammer brother. It can cause the ground to vilently shake when it stomps on the ground, causing Mario to be stunned if he is on the ground.

Hot foot

 * A flame from a candle in a castle that can follow you around. Like Boo it will only move when you turn away from it.

Buster Beetle

 * A beetle that can throw ice blocks at you. Unlike normal buzzy this doesn't leave a shell behind when stomped on.

Nipper

 * A plantlike enemy found on the ground that cannot be killed by stomping on.

Kuribo's Goomba

 * A Goomba wearing a shoe. You can get it if you bop the Goomba off a block. Stomping on it or firing it, however, will kill the shoe as well.

Parabeetle

 * An enemy whose backs can be ridden on in the sky world.

Ptooie
A piranha plant which walks on the ground. It has a spiked ball which it raises and lowers with its mouth, because of this and its resistance to most attacks it forces Mario to take a leep of faith between the pirahna and the spiked ball. Some of these enemies are based in pipes and tend to remain sticking out unlike normal piped pirahna.
