This werewolf loves to party, he can't seem to get enough. He parties so hard that he hypnotizes everyone to drop what they're doing and party with him. The boss uses Bill's power of party hypnosis to keep humans from leaving the island and keep inhabitants of the island happy. Everyone loves a good party, Especially this party animal!
Each mastery level adds another card to the cardpool for defeating Bill. Each of the bronze, silver, and gold mastery levels unlocks a new card, while it takes all three diamond and onyx levels to unlock a single card.
