Submarine Yoshi



The Yoshi Submarine was a form of Yoshi that could be transformed into in Super Mario World 2: Yoshi's Island by touching a Morph Bubble.

The two tasks it performed were travel through bodies of water (because normal Yoshis could not go any deeper into water than the very top), and shoot homing torpedoes (because Yoshis couldn't attack in special forms).

The Yoshi Submarine reappears in Yoshi's Island DS; however it no longer shoots torpedoes.

Trivia
Interestedly, in the artwork image in this article; the torpedoes the Brown Yoshi just launched actually resembled as Yoshi faces at the front while the propeller exists in the back. These types of torpedoes can't be recognized in the game like the artwork, most likely due to pixel limitations.
