Flame Chomp

Flame Chomps (also named Fire Chomps) are enemies that resemble Chain Chomps, but differ in several ways. First, they are not restricted by chains, instead floating along with a line/tail made of fire. At any time, they may shoot fireballs at Mario or Luigi. The fireballs are taken directly out of their four-fireball line/tail. When it runs out of fireballs, the Flame Chomp will explode, damaging the Mario brother if they are within the blast radius. Also, unlike Chain Chomps, they are vulnerable to stomps and Fire Mario/Luigi's fireballs. They live mainly in the skies.

Super Mario Bros. 3
In Super Mario Bros. 3, Flame Chomps (under the name Fire Chomp) only appear in Worlds 5 and 6. They float along as Mario and Luigi navigate the stage, harrying Mario's progress on the small platform with their fireballs, especially in World 5-9, where the player has a limited amount of platforms he can jump onto in addition to an automatically-scrolling screen. They can only use four fireballs; when used up, Fire Chomps will explode like Bob-ombs. They can be defeated with stomps, fireballs, hammers, Starmen, and tail whacks. In this game, their faces only appear when they shoot their fireballs.

Super Mario 64 DS
In the remake, Super Mario 64 DS, Flame Chomps replace Kuromames. They remain motionless and have the same effect as them, shooting a flame at Mario when he approaches, and they can be eaten by Yoshi, allowing him to breathe fire. Because of their replacing Kuromames, it is the first, and so far, only appearance of them where they don't self-destruct after running out of fire.

New Super Mario Bros.
Flame Chomps return in New Super Mario Bros., again with a four fireball limit. They only appeared in World 7-1. They can be defeated by just jumping on their heads. Unlike Chain Chomps, which are almost invincible (bar a few techniques and powers of special characters), Flame Chomps can safely be jumped upon. Doing so knocks them out of the sky. Once they run out of fireballs, they explode like Bob-ombs.

New Super Mario Bros. Wii
In New Super Mario Bros. Wii, Flame Chomps are a bit more common, appearing in World 2-6, World 8-3, and World 9-6. Flame Chomps have the same attack pattern as in the previous game but have now developed a new attack in New Super Mario Bros. Wii. When this enemy runs out of fire, it flashes red and self-destruct seconds later, but not before chasing Mario much faster than it was originally doing. They can be defeated with a single jump like in previous games, and can once again be defeated with fireballs.

New Super Mario Bros. 2
In New Super Mario Bros. 2, Flame Chomps exclusively appear in World 6-B. It acts exactly the same as in New Super Mario Bros. Wii, when this enemy runs out of fire, it flashes red and self-destruct seconds later. They can be defeated with a single jump, just like in the previous games.

New Super Mario Bros. U
In New Super Mario Bros. U, there is only one Flame Chomp in the entire game, located in a hidden room in Peach's Castle-3: Rising Tides of Lava. It must be bounced off of to obtain the stage's final Star Coin.

Fire Chomps, under the new name "Flame Chomp" also appear in New Super Luigi U. In this game, it is shown that Flame Chomps can use up all of their fireballs on their "tail" to create a much larger fireball. Flame Chomp Ferris Wheel, as its name implies, have Flame Chomps as the key enemy.

The Adventures of Super Mario Bros. 3
Fire Chomps make several appearances in The Adventures of Super Mario Bros. 3, such as in the episode "The Beauty of Kootie", where several Fire Chomps act as crew members on Bowser's Doomship.

In the show, Fire Chomps don't have a fireball tail, and have flexible borders around their eyes (which this time are red) and mouth.

Nintendo Adventure Books
A Fire Chomp appears in Koopa Capers, prowling a cave in the Magma Pits. While Luigi is fleeing from the Hot Feet that also live in the cave, he can choose to either rush blindly ahead, or take his time; if he chooses the latter, he will just narrowly avoid the Fire Chomp, but if he picks the former, he will run into and be scorched by the fireballs of the Fire Chomp, causing a Game Over.
