Cartoon Cat

To progress in this add-on, you have to kill the zombie-like Cartoon Cats; they drop ink, which you can use to craft items to summon the boss and a very powerful ink sword. To obtain Cartoon Cat's mouth, you will need to kill a mini-boss located in a structure that looks like a school. If you defeat the boss, you complete the add-on and can continue surviving against the 7 forms of Cartoon Cat.
