The Rocket is an item in Super Mario Bros. 2. It can be randomly plucked from the ground, just like Vegetables, and acts as the "door" to the next level, taking Mario, Luigi, Toad or Princess Peach upwards. After a certain height, the player's character jumps out of it, and it explodes shortly afterwards. It only appears in Worlds 4 and 7 of the game.
It also appears in Yoshi's Island DS where Yoshi goes inside a hut and comes out of a launch pad. It appears in Level 5-4 The Fort of Moltz the Very Goonie, and Level 5-8 At Last, Bowser's Castle!.
The Rockets that appear in the background of Mario Kart 7 version of Rainbow Road bear similarity in appearance to those of Super Mario Bros. 2.
