Wario Land 3: Part 67: Bank of the Wild River (Green Chest)

Using Wario's improved swimming from the Frog Prince's Glove, he swims through the level's bottom water current at the start to reach a new room. In that room, he climbs vines to a doorway on the other side and picks up the Green Key. In the next room, the Green Chest is present but unreachable because the water current before it is too strong even for Wario's super swim. He must go around the obstacle and encounters a boss, a rat‑faced puffer fish named Pesce. Pesce cannot be fought directly; he will eat Wario and spit him out through the strong current. Wario uses a dragonfly as a floating platform and lures another fly to bring cheese, causing Pesce to chase and eat it, which makes Pesce fat. As Pesce becomes fat, he clogs the strong current, allowing Wario to reach the Green Chest. The Green Chest contains a living Statue that builds more climbable fences in the Tower of Revival and The Tidal Coast.
