Lake Winimahatikihaha is the location of Dr. Heinz Doofenshmirtz's hideout in the episode "The Magnificent Few." The lake is nestled in fog-shrouded hills and is in view of Clem's Carnival on the shore. The hideout has a room filled with lava that Vanessa calls the "Death Chamber." The chamber has a few flaws though: an escape hatch in the ceiling and a self-destruct button that the prisoner can reach. The whole design is suspect as there is a ramp leading right into the control room.
