بيتا بيتا نو مي

This Paramecia-type Devil Fruit hands its owner command over mucus, generating and directing the sticky substance at will and making them a Mucus Human. The eater is Trebol of the Donquixote Pirates. The Japanese onomatopoeia betabeta conveys the idea of something sticky or clinging, matching the goo the power creates. VIZ and the Episode of Sabo dub call it the Stick-Stick Fruit, whereas the main-series Funimation release goes with Sticky-Sticky Fruit instead.

The fruit's core benefit is an endless supply of mucus, which the user deploys to pin down movement and glue themselves onto any surface, with enough adhesive strength to hoist an entire ship. Since that boundless slime looks like the wax of the Doru Doru no Mi or the poison of the Doku Doku no Mi, two comparable fruits, the power can be mistaken for a Logia. Trebol pulled this trick on Luffy, who drove a fist into the mucus coating under the belief it was flesh and was stunned when his blow did nothing; the user can even tint the slime, as Trebol did when shaping part of his coat to look like his real body. The mucus catches fire easily and detonates fiercely when a spark touches it, a hazard Trebol turns to his benefit. His perpetually dripping nose may or may not stem from the fruit, but it lets him spray snot at enemies. Should the user suffer serious injury, control over any generated mucus collapses, opening them up to further harm. Beyond this vulnerability, along with the usual weaknesses shared by all Devil Fruits, the ability carries no other known flaw.

Trebol employs the power to cling to roofs and walls and to stretch his reach, snaring distant targets and locking them in place. He can fire mucus with such force and accuracy that he pierced a wall while nailing a fly between its eyes, and he wields heavy objects on a mucus tether like a flail. His techniques include Beta Beta Chain, a mucus rope tipped with an anchoring end, and its follow-up Beta Betton Meteora, which flings a seized object at a foe. With Hanamizu Shinken Shirahadori he manipulates the snot from his nose to parry sword strikes, while Beto Launcher and Beta Betton Launcher pelt opponents with flammable, adhesive spheres that pin them wherever they land. He also masqueraded as a Logia by wrapping his gaunt frame in a thick shell of mucus, letting attackers waste blows on empty space.
