Runk
When it appears
As a tier-3 Nexomon, it only turns up in the grass after you beat Ross and Nora in Laboratory Ruins Boss, or from the start in Custom Mode with high-tier encounters allowed.
Capturing
Its favourite foods are Cream Puff, Flan and Pandulce, Rubby's, as every stage of a line shares the first one's. Feeding it one adds 15 to your capture chance, where other food adds 5. Catching a Nexomon explains how the whole chance adds up.
Evolution
Cosmic
Every wild one has a 1 in 4,000 chance to be cosmic at first, and 1 in 3,500 later in the story. What improves the odds is on the Nexomon page.
