Cow

The Cow is a ridable animal in Scribblenauts and Super Scribblenauts. If you kill them they turn into Ground beef,witch they will eat. If you interact with them, they will drop Buttermilk in a Glass. If you place a Bull next to a cow the Bull will protect the Cow. By feeding them meat, they will become agressive for a few seconds and then die. This may be mad cow disease.

Uses
Milking (so you don't have to write lots of milk, just use a cow) Riding (not the best mount unless you use adjectives)

Trivia

 * In Super Scribblenauts, an adjective "Cowlike" exists, which makes it similar to a cow.
