This is just the decor accessory to spice up a ''ho-hum'' bathroom. This is a rubber monster with suction cups that attach to the underside of the toilet lid. When the unsuspecting guest lifts the lid, up pops the monster, and the unsuspecting guest keels over, dead. You were never all that fond of this particular guest anyway.
This is the Toilet Monster preferred by all leading hotel chains, as well as Buckingham Palace.
