Uncle Infinite is a recolor of Papa Bolt. He appears as a humanoid Yo-kai with brown skin, grey hair and a grey beard. He wears a purple sleeveless kimono with gold accents, including a large golden rope coiled in three circles on his back. He rides a dark storm cloud.
Uncle infinite rarely appears at the summit of Mount Wildwood on cloudy and rainy days and nights in the mounted binoculars.
A useful trick for befriending him is, if you call Drizzelda and Ray O' Light to their Yo-kai spots, you can ask them to change the weather from rainy to sunny and back over and over. Each time you do, the Yo-kai in the binoculars will change. When your Yo-kai meter reads S-Rank you can go to the binoculars and battle Uncle Infinite.
