Slurpent is a large snake-like Yo-kai with red scales, and a yellow underbelly, with eight thin purple tongues dangling from his blue lips. He has yellow eyes with black sclera and a yellow and blue marking on its head. On his belly there is a 8-shaped brown symbol, and a blue "rattle" of the same shape is on the tip of it's tail.
Slurpent's ability is to make someone irresponsible from the touch of his eight tongues.
Yo-kai Watch 2
Befriend the following Yo-kai to unlock Slurpent's Medallium page. In Yo-kai Watch 2, they were all Crank-a-kai-exclusive Yo-kai from the past.
Yamatan is a portmanteau of part of "Yamata no Orochi", specifically, the "eight branches" (Japanese: 八岐,Yamata) part and "tongue" (Japanese: タン,Tan), referencing the 8 long tongues this Yo-kai sports.
Slurpent is a portmanteau of "Serpent" and "Slurp", referencing his 8 long tongues.
Octoserpie is a portmanteau of "Ocho (eight)" and "Serpiente (snake)", referencing his 8 long tongues.
Yamatan, like Venoct, could be based on the Yamata no Orochi, but while Venoct's design mixes it with the image of the ninja snake summoner Orochimaru from Jiraiya Gōketsu Monogatari, Yamatan is much closer in appearance to the great serpent. The Kojiki (a text on Shintoism and the origins of the country from the 8th century, and the oldest written record in Japanese history) describes Orochi as an enormous eight-headed snake with a bloody red belly and eyes like winter cherries, large enough that its body can lie across eight mountains and eight valleys, and plants and moss grow all over it. The number eight is a symbol of the infinite in Eastern culture, thus its recurrence symbolizes the creature's immeasurable power and girth.
Slurpent is technically the strongest Yo-kai in overall stats when befriendable in Yo-kai Watch 2.
Slurpent is by far the only Legendary whose Merican version debuted before him in the anime.
