Loch Nestor

Loch Nestor is a puffer fish in the game Super Mario World 2: Yoshi's Island and Yoshi's Island: Super Mario Advance 3. It only appears when Yoshi has been morphed into a submarine, and if it is hit by a torpedo, it simply grows two times larger and chase Yoshi. After it is hit three times, it explodes.

Trivia

 * Loch Nestor derives its name from the Scottish lake, which is the home of the famous and mysterious Loch Ness Monster (also called Plesiosaurus), also known as Nessie. Probably Loch Nestor was named after the Loch Ness Monster. The name Loch Ness has been mixed with the name Nestor (a given name), to create this fish's name.
