Super Mega Ultra Shroom

A Super Mega Ultra Shroom is a Mushroom that was mentioned by Mimi in Super Paper Mario. There is no such item as this-Mimi was disguised at Merlee, and made up the item, saying that she'd give it Mario and Co. along with the Pure Heart if they signed a contract for them to pay 10 million Rubees. Again, this mushroom does not exist, and if it did, there probably would have been no use for it anyway.
