Sho Sho no Mi

The Sho Sho no Mi (小便小便) is a Paramecia-type Devil Fruit in which the user can make opponents, regardless of their age to literally pee their pants. Sho for “Pee”, in both Viz Manga, and the FUNimation dub, it is called the Pee-Pee Fruit. The fruit was originally given to Skelly as a present for his birthday by Samhain and then was eaten by Skelly.

Strength and Weakness
This fruit strength is not really for combat or defensive purposes, Skelly can make people regardless how old they are and how long they can hold it. Skelly can make them pee their pants, another strength is that the user will never pee themselves. Which seems to be a blessing for Skelly since he is still a little kid, the user will suffer the standard weakness of the devil fruit.

Attacks
Shitagi (下着, Literally Meaning "Pee Yourself") Skelly is able to literally make anyone regardless of their age pee their pants, this attack seems to be more of a laugh for Skelly and his friends. It might be an annoyance to an opponent, but that's about it.
