A orange daruma Yo-kai, Dulluma has four pairs of blue markings, humanoid arms and short legs, dark peach noses, white eyes with no visible pupils, and black facial hair. He has an outer shell in which it has pale peach skin and having a serious. His actual appearance however, has pale blue skin, drooping facial hair, and holding a dull expression (hence Dulluma's name origin).
As mentioned in his medallium bio, he is shown to be dull and sluggish.
Whoever Dulluma inspirits, they will become listless and unmotivated.
Beyond that, Dulluma has a dense body, with a particularly noteworthy hard head covering that contributes greatly to his Soultimate Move. He also uses this whenever it is blocking.
Dulluma appears in the Catwalk, the Desolate Lane, and under cars and vending machines everywhere in Uptown Springdale.

Receiving food (disliked): "Hard to eat..."
"Dulluma" is a portmanteau of dull and daruma.
"Darudaruma" instead combines with darudaru (sluggish, languid).
"Tentelento" combines "Tentetieso" (stupid) and "Lento" (Sluggish).
Dulluma's design is based on a daruma doll, a wooden figurine representing Bodhidharma, the Buddhist monk credited with bringing Zen Buddhism to China, famous for being so dedicated to religious practices he'd give up all his limbs for their sake. They're sold at temples with blank, pupil-less eyes, because the owner will then draw in one pupil when setting a personal goal, then the other when they achieve it, so that the "incomplete" doll will remind them of what they set out to do every time they look at it. After New Year's the dolls are taken back to the temple and burned in a sort of burial rite, after they're thanked for their services.
Perhaps as a humorous twist, Dulluma makes people lazy and listless, instead of focused on their goals.
