Arfs are somewhat rare enemies. They are stationary, but can summon Arf Dawgs from their doghouses. They can also whack the player with their doghouses if the player gets too close. They take three hits to destroy making Arfs one of the most durable enemies in the game.
Sandy has unused dialogue that she would say when she encountered Arf.
Arf also has an unused animation for when it was lassoed by Sandy.
