Lunge Fish

Lunge Fish are large, bucktoothed that appear throughout Yoshi franchise. They are predators of Yoshis, whom they try and swallow whole. Its name is a pun on "lunge" and "".

Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3
Lunge Fish first appear in Super Mario World 2: Yoshi's Island, where they hide in the water, and, like their name implies, will lunge at Yoshi as he passes by. Occasionally, a Lunge Fish will stick its head out of the water. Yoshi can then throw an egg at the fish to momentarily stun the creature, or he can defeat one outright by spitting an enemy out at it. If Yoshi falls in the water, a Lunge Fish will attempt to swallow Yoshi and Baby Mario whole similar to how a Boss Bass does.

As shown by graphics in the source code of pre-release builds, Lunge Fish seems to have started out as a bespectacled worm-like creature, labeled "nomo" (an abbreviation of the Japanese name) in the files.

Tetris Attack
In Tetris Attack, a Lunge Fish appears as a playable character and an opponent who is paired with Flopsy Fish. It replaces Neris, the sea fairy from Panel de Pon. In this game, it is depicted as a slight friend of Yoshi's, enchanted by Bowser and Kamek to work for them. It also notes that it really does not like Yoshi much, claiming that he gives it indigestion.

Yoshi's Island DS
In Yoshi's Island DS, Lunge Fish appear again, with their sprites appearing to be the desaturated Yoshi's Island: Super Mario Advance 3 ones with added shading. They act exactly the same. In one level, Yoshi must travel in a boat over a lake infested with Lunge Fish.

Yoshi's New Island
In Yoshi's New Island, they prominently appear in the level Lose the Lunge Fish. From this game onwards, their lunging-while-inhaling behavior is replaced with a Boss Bass-esque leaping, showing off their entire bodies. However, they still function in the same pattern as before, sinking below the water before rising up and forwards in a jerky arc.

Yoshi's Woolly World / Poochy & Yoshi's Woolly World
Lunge Fish appear in Yoshi's Woolly World as an enemy in some stages with water. In this game, Lunge Fish are modeled on coin purses, with their lips being made of coin purse clasps. Yoshi can defeat them with yarn balls or watermelon seeds, earning a handful of beads, but they will respawn quickly. They act as they do in Yoshi's New Island, but are larger and move through the air slower. They appear in Rollin' Down the River, King Bowser's Castle and Wonderful World of Wool.

Yoshi's Crafted World
Lunge Fish reappear as enemies in Yoshi's Crafted World during the level Ride the River, where they sit in place in the background, jumping out whenever Yoshi crosses their line of sight, and can take down platforms while trying to eat him. At the end of the level, one instead pursues Yoshi horizontally, taking down several moving platforms while repetitively leaping. Near the end of the level's flip side, two can be seen looking back and forth instead of in a single direction, and as such can leap in multiple directions.

Super Mario-Kun
In volume 14 of the Super Mario-kun manga, a Lunge Fish is depicted as being able to use electricity on its enemies, based on the real-life. Mario sees a Winged Cloud that gives out a blue watermelon. Mario makes Yoshi eat it, which then freezes the Lunge Fish.
