Big Chain Chomp

Big Chain Chomp is an especially large variety of Chain Chomp. Large Chain Chomps appear in many other games, such as Super Mario 64, Super Mario Sunshine, and the Mario Kart games; however, the ones in those games are treated as the normal-sized Chain Chomps.

Super Princess Peach
The Big Chain Chomp first appears in Super Princess Peach. This Chain Chomp, despite its name, is not attached to any chain, but it is larger than a normal Chain Chomp. It mostly acts as an obstacle that Princess Peach and Perry need to avoid, and is usually found bouncing down hills provided with gaps in which the princess and her umbrella may hide. Their attack patterns can be thought of as similar to those of the Chomp Sharks, and some of them act similar to Chomps.

According to the game's Glossary, Big Chain Chomp is "A giant Chain Chomp. Very dangerous!".

New Super Mario Bros. Wii
A Big Chain Chomp also appears in New Super Mario Bros. Wii, in Iggy's battle in the castle of World 5, after Kamek's Spell. This Big Chain Chomp pulls a rail-based carriage Iggy rides in, as it hops around the platforms if the room. When Iggy is stomped, the Big Chain Chomp gets red and angry with the sound of a train whistle, akin to Wiggler, before beginning to temporarily move faster. This seems to stand in for having Iggy retreat into his shell. Once Iggy has been stomped three times, the Big Chain Chomp is defeated along with its master.

New Super Mario Bros. 2
A Big Chain Chomp, possibly the same one from before, also appears in New Super Mario Bros. 2. It acts much the same as the one from the previous game, but is somewhat smaller, and has more paths to take due to the different room layout. It is defeated the same way as previously.

Super Mario Maker
Big Chain Chomps appear in Super Mario Maker and Super Mario Maker for Nintendo 3DS alongside other giant enemies. They can be created by dragging a Super Mushroom onto a normal-sized Chain Chomp.

Super Mario Odyssey
Big Chain Chomps are set to appear in Super Mario Odyssey alongside their smaller counterparts in the Cascade Kingdom.

Paper Mario: Sticker Star
In Paper Mario: Sticker Star, three Big Chain Chomps need to be used in order to get to Petey Piranha who is the guardian of the fifth Royal Sticker in Rumble Volcano. One also appeared in Chomp Ruins. They cannot actually be harmed (outside of jumping on them pre-battle when they are asleep, which is mitigated by the fact that they, like all enemies and even Mario, recover health when asleep), instead, they are actually the basis of a puzzle. The player has to hammer their post down while they are asleep, then engage them in battle and use any attacks before they wake up. Afterwards, the Chain Chomp will then lunge at the player, causing 10 damage and ending the battle early due to escaping confinement. This attack cannot be blocked.

Paper Mario: Color Splash
A Chain Chomp named Princess becomes a Big Chain Chomp in Paper Mario: Color Splash, by way of Kamek's magic. In this form, she is made out of interlocking pieces of cardboard.

Mario & Luigi: Paper Jam
A single Big Chain Chomp appears in Mario & Luigi: Paper Jam. Iggy and Morton use the Big Chain Chomp for one of their attacks.
