Chapter 13 (Flashback)
They are the K: BTS series' incarnation of Nidoo, a enemy from Kirby's Dream Land 3 and Kirby: Triple Deluxe.
Much like their fellow Dark Matter, Nidoos have pale black skin and lavender eyes. Originally, they were going to look much like they appeared in Kirby's Dream Land 3.
While they are as aggressive and violent as their fellow Dark Matter, Nidoos are maliciously mischievous and they tend to turn themselves into objects so that people would either not notice them or pick them up while mistaking them as a another object such as a book.
Nidoos are shape shifting beings much like 0 is but they tend to turn into objects so that people do not notice them or mistake a Nidoo for a different object instead of turning in a more monstrous form.
Kirby: Behind the Scenes 3: Chronicles of DarknessEdit
A single Nidoo marked the species' debut in Chapter 13 along side a Mariel, Minion Matter and a N-Z.
