The Raven is an enemy that has only appeared in Battletoads and its Game Boy port, Battletoads in Ragnarok's World. It appears in Level 2, Wookie Hole, in both of the games. Although they seem powerless, they will fly across the screen and may even cut the player's rope with their sharp beak, causing them to lose a life instantly.
If the player is to hit a raven, its corpse with fall, leaving behind a white object (most likely to be a fly swatter). The object can be grabbed by the player and used to attack other enemies.
