|Bullet Bills are large black bullets launched by Bill Blasters. Bill Blasters are placed strategically throughout many levels. They can even be found on the ground, where even small Mario can't duck beneath the bullets flying his way. Do your best to avoid them, or stomp them out of the way.
||Missile Bill resembles a Bullet Bill that is flashing red. Missile Bill locks on to a target (like Mario), and will turn around once if it misses. Once it turns around, however, it will continue to travel in a straight line until it flies off the screen or is defeated.
|The Angry Sun is a considerably small sun with an angry face. They are the second least common enemy of the game, making only two appearance; one in the World 2-Quicksand and the other in the World 8-2. To attack Mario, the Angry Sun swoops down in an attempt to hit the plumber before returning to the sky. They can be killed with a Koopa shell, a hammer from Hammer Mario, or by crashing into Invincible Mario.
|| Spikes are small green turtle-like enemies with an unusual form of attack: they pull spiked balls out of their mouths before throwing them at Mario . Like Lakitus, they have unlimited amounts of ammo. The spiked balls fly straight across and they can even pass through blocks and terrain. Spikes are vulnerable to all types of attack.
|Bob-omb is a living bomb. They are often launched by cannons, but occasionally they appear walking on the ground. If Mario stomps on one, it will become stationary and capable of being picked up and used as a weapon. However, it will explode in a few seconds, even if Mario is still holding it. Later on in the Bowser's Tanks, Bob-ombs self-destruct after a few seconds from when they appear. They can't be destroyed with fireballs, but they can be taken out by explosions from other Bob-ombs.
||Chain Chomps bear a resemblance to a ball and chain and have very dog-like behaviors, including barking. They're attached to a block, but if 160 seconds go by, they are set free. There are four ways to defeat Chain Chomps: using a Star, throwing a Koopa shell or a hammer at it as Hammer Mario, and stomping on it as a statue from Tanooki Mario.
|The Fire Snake is a flame with four fireballs behind it. Fire Snakes chase Mario in an effort to set him on fire. They hop from one location to another, in whatever direction Mario happens to be. They can only be defeated by either hitting it with a Shell or Hammer, by using an invincibility star, by hitting it with a raccoon tail, or a stomp from Statue Mario.
||A Fire Chomp is a cousin of the Chain-Chomp, but it's held together with four fireballs instead of a chain. They are capable of flying, and they spit fireballs at Mario. When they run out of fireballs, they chase Mario before they explode. They can be defeated with stomps, hammers, Star, and tail whacks.
