Whale (Mario)

Whales are enemies and obstacles in Super Mario Bros. 2.

Strategy
Whales are found only in Level 4-2. When Mario encounters a Whale, it'll spray water from its blowhole and it hurts him. Mario will fall into the water and won't jump on its tail if he's uncareful. Whale act as platforms in the series. When he's on the blowhole, it won't spray water. Some enemies are on Whales, like Shy Guys and Snifits.

Note: Whales can't die from being killed by veggies or go back to the water.
