Magical Potion

Magic Potions are items that Mario and his friends discover in the land of Subcon during the events of Super Mario Bros. 2. When picked up and thrown to the ground, a Magic Potion allows Mario and friends to enter Subspace, where they can find Gold Coins and Mushrooms. In certain areas throwing one on to a Vase will create a door that will act as a Warp Zone and allow you to warp to a different World. In Super Mario Advance, after finishing the game, one can find Yoshi Eggs.

In The Super Mario Bros. Super Show!, King Koopa sometimes pulls out a Magic Potion at the end of an episode, usually when he is outmatched by Mario's group, in episodes such as Bad Rap and Mario Meets Koop-zilla and throws it, creating a Warp Zone for him to escape.
