Lakithunder

Lakithunder is the boss of World 7 in New Super Mario Bros. He is a large, black-shelled Lakitu with stylized sunglasses and a black scarf who rides a yellow-eyed dark cloud; he can swoop towards the player and also throws Spinies like the other Lakitus, though the Spiny Eggs he drops bounce around erratically. He can even let thunderbolts loose from his cloud that strike directly below him. The player must jump on Lakithunder's head three times when he swoops down low in order to defeat him.

As World 7 is a secret world, he is one of two bosses not encountered on the standard path through the game, along with Mega Goomba.
