Moofish

A Mōgyo is an enemy that appears to be a combination of a cow and a fish from the Tree Zone level In the Trees in Super Mario Land 2: 6 Golden Coins. Mōgyo are found swimming in the tree sap. If the player enters the sap it is in, the Mōgyo will charge at them horizontally. To defeat this creature, the player has to either jump on top of it or throw a fireball at it.
