Thankfully, his surrogate daughter and longtime friend, Marceline Abadeer, had managed to cobble together a pin made out of stolen Venture Tech and demon magic and sneak it onto his crown (the source of his Insanity) that reduced it from being completely bonkers to simply very eccentric. Now able to think more clearly, Ice King, joined Marceline, Gunter the Penguin and many others seeks to expand the Ice Kingdom, and can actually focus long enough to do so now!
