Skull Boxes are black artillery that first appeared in Super Mario World. Gloved hands from the Skull Boxes release Torpedo Teds at Mario. Much like Bill Blasters, the Skull Box can be destroyed only by Mega Mario.
Super Mario series
Super Mario World
Super Mario Galaxy
Skull Boxes also appear in Super Mario Galaxy, where they sport a new look and new name: Ted Blasters. They are most often found in the water, and now can be destroyed by leading a Torpedo Ted right back at them.
New Super Mario Bros. U
Skull Boxes, as well as the Torpedo Teds, return in the Wii U game, New Super Mario Bros. U. They behave and look exactly as they do in Super Mario World, and appear in Larry's Torpedo Castle; they are once again invincible. Targeting Teds and Red Skull Boxes debut in The Mighty Cannonship level, being both obstacles and weapons that appear in the fight with Bowser Jr. While Torpedo Teds reappear in New Super Luigi U the Skull Boxes are absent.
Super Princess Peach
Skull Box return alongside the Torpedo Teds in the game Super Princess Peach, where they are invincible.
