Moby

The Moby is an enemy featured in The Adventure of Link and in the animated series.

The Adventure of Link
In The Adventure of Link, the Moby is a type of orange bird found in swamps. It drops out of the sky and flies directly towards anyone in range of it. Link must use his sword attack just right so that he can hit it before it flies into him. If Link is hit by the Moby, he loses experience points.

Animated series
A single Moby appears in the "Cold Spells" episode of the animated series. While Princess Zelda is inspecting Link's messy room, a Moby flies in through the open window and attacks her. Zelda hits it with a nearby jar and the Moby lands near Link's pile of dirty clothes, and when the princess pushes its head further in, it is so disgusted by the smell that it flies away.
