Lakitu's Cloud

Lakitu's Cloud (originally known as Jugem's Cloud) is the cloud with the smiley face on it that Lakitu usually inhabits.

In Super Mario Bros. 3, Lakitu's Cloud could be used by the player to skip a level he disliked.

In Super Mario World, Super Mario World 2: Yoshi's Island, Super Mario 64, and New Super Mario Bros., after taking out the Lakitu inhabiting it (if there is one), the player could jump on Lakitu's Cloud to reach places that he could nomally not get to.
