The Lunge Fish is an enemy in Super Mario World 2: Yoshi's Island.
Super Mario World 2: Yoshi's Island
Lunge Fish first appeared in Super Mario World 2: Yoshi's Island, they hide in the water and will lunge at Yoshi when he passes by. Occasionally, a Lunge Fish will stick its head out of the water. Yoshi can stun it by throwing an egg at it, or he can defeat it by spitting out an enemy at it. If Yoshi falls in the water, a Lunge Fish will attempt to swallow him.
Yoshi's Island DS
Lunge Fish appear again, in Yoshi's Island DS. They act exactly the same from the previous game.
Yoshi's New Island
Lunge Fish reappear in Yoshi's New Island, they are prominently found in the level Lose the Lunge Fish. In this game their lunging-while-inhaling behavior is replaced with a Boss Bass-esque leaping, which reveals their entire body. However, they act the same as before, sinking below the water before rising up and forwards in a jerky arc.
Yoshi's Woolly World
Lunge Fish reappear in Yoshi's Woolly World. They are found 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, but they'll respawn quickly. They act the same as they do in Yoshi's New Island, but are larger and move through the air slower.
