Minus Watch

The Minus Watch is an item which is used as a portal to The Minus World. It was first owned by Bowser, and was stolen by Daisy. After Professor E. Gad fixed it, he used it to bring Dragon Toadstool and Mario back from the Minus World. Daisy then used it to trap Bowser in the Minus World.

Trivia

 * The Minus Watch is actually taken from Super Mario Bros. Z, another fanmade project, made by Mark Haynes/Alvin Earthworm.
