Moofish

A Mōgyo is an enemy that appears to be a combination of a cow and a fish found in the Tree Zone in Super Mario Land 2: 6 Golden Coins. Mōgyo are found in the trunk level of the Tree Zone swimming in the tree's 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.
