Torpedo Ted
Torpedo Teds are, as their name implies, a torpedo, much larger than a Bullet Bill, moving underwater and initially found in Soda Lake in Super Mario World, it also can be founded in Super Princess Peach. Black boxes with a skull and crossbones drop out Torpedo Teds. They move fairly fast and are hard to move around in Soda Lake's close quarters.
Torpedo Teds make a guest appearance in Stage 2 of Turtle Zone in Super Mario Land: 6 Golden Coins. They appear as Bill Blasters found only underwater.
Torpedo Teds are also found in underwater areas of Super Princess Peach. Many are under the influence of the Vibe Scepter, turning them into Glad Torpedo Teds.
