Darkfreeze Shajio

Dark Shajio are strange enemies that come in the colors of red, blue, and green. Dark Shajio look like elemental Blowhogs, but with a few key differences: they have two legs and their body colors are swapped with their snout colors. They come in different colors that indicate what hazard it uses to attack: red for fire, blue for water, and green for acid. The eyes of Dark Shajio change color whilst attacking.

In Pikspore
PS undefined Dark Shajio appear in PikSpore, very late in the game. Here, they are not actually Blowhogs; instead, they are blobs of Darkfreeze solidified into Blowhog-like forms. They shrivel up and turn dark blue when defeated. There are also subspecies called Giant Dark Shajio and Aero Shajio.
