Swosh makes anyone he possesses have a wide and forgiving heart as big as the ocean, although that forgiveness can really go overboard in some cases.
Befriending: "Your heart is wider than an ocean... We are...same."
Daily battle: "Oh! I'm so glad you stopped by! I think I nearly overslept again... Now, shall we battle? It always help keep my rough waters at bay."
Yes: "All right, human... Let's battle! Gw...GWARR... GWAARGLE!"
No: "Oh. Well then, maybe I'll just catch a few more winks."
Befriending (failed): "...Oh my, I'm so embarrassed! Did my waves of anger surge to the surface yet again?"
Befriending (success): "Oh! I'm so happy you've returned! Do you see, my friend? Your heart, deep and wide, has kept me at peace! May our alliance last through storms and swells! [...] Heh! I hope you still come back to visit from time to time!"
Its random names are: Oshan, Agua, Seadude, and Wintea.
As of Yo-kai Watch 3, Swosh has the 2nd highest HP stat out of every Yo-kai only being beaten by the Merican Legendary Bourgeois G.
Swosh is based on the Umibōzu (Japanese: 海坊主,Umi-bōzu, literally "sea monk"), which is also his Japanese name. This youkai appears as a pitch-black, oily giant emerging from the sea causing huge waves, staring down at ships with huge brilliant eyes. The name "monk", like for other similarly named youkai, is owed to its smooth, round head, like a ordained Buddhist monk's shaven scalp. Seasoned sailors know to remain silent and sail by quietly if they spot one, because this youkai dislikes screaming and loud noises, and will promptly smash the source of its annoyance to bits if provoked. Some sources claim the Umibozu s actually a giant octopus, or an enormous sea lion.
"Swosh" could refer to the sound of the rolling waves.
His brazilian portuguese name Chuá also comes from this.
