Bovine Savior

An axolotl tells the player - a cow - that all plants are evil. The cow must conquer the plants the only way he knows how - by eating them. The player must clear the board by eating all of the plants without losing all health or being caught by the rancher. 

The puzzle comes by learning which plants are dangerous and what they do. The player can also upgrade the cow by talking to the axolotl. These upgrades allow the cow to eat more while taking less damage, or being affected less by the plants.
