Mr. Saturn

Mr. Saturns are an alien species from the EarthBound/Mother series. They also appear in Super Smash Bros. Melee, Super Smash Bros. Brawl, and Super Smash Bros. for Nintendo 3DS / Wii U as weak tossable items. The Mr. Saturns walk around the stage until someone picks them up. After a while, the Mr. Saturn will disappear. They can be picked up and thrown at another player for minor damage. However, there is a high chance that a thrown Mr. Saturn will break a shield. Peach, when doing her Vegetable move, has a small chance of grabbing a Mr. Saturn instead of a vegetable. In the Onett mission of Adventure Mode in Melee, Mr. Saturns are the only items that appear.

An update of Super Mario Maker added a Mr. Saturn as a Mystery Mushroom costume unlocked via Event Courses. It will also add Master Belch, a boss from Earthbound.
