Lakithunder

Lakithunder is the World 7 boss in New Super Mario Bros. He is a Lakitu with sunglasses who rides a dark cloud; he is a member of the Koopa Troop. As the name implies, he can shoot lightning directly under him, and also throw Spinies like the other Lakitus. The Spiny Eggs he drops bounce around erratically, unlike those of normal Lakitus. Mario must Jump on Lakithunder's head three times, when he swoops down low, to defeat him. Like Mega Goomba, Lakithunder does not need to be defeated to complete the game, as World 7 is optional.
