This is the Adventure Time BMO inspired bathmat made and sold by Etsy shop SeamsGeeky (who also sells matching hand towels and bath towels). They cost $65 and help absorb water when you step out of the shower so you don't slip and bust your ass. "Sit on my face-screen." BMO, no! I'm not so sure I want you hanging out in my bathroom anymore. "That makes BMO sad." Fine, fine, you can still watch me pee but no talking, I need to concentrate.
Thanks to Tank, who would really look great with me sitting on the cannon, waving a pirate falg.
