PTP | Kedamono!

Kedamono is a purple-furred, anthropomorphic wolf that wears orange boxers with a yellow star pattern on top and an ever-changing Noh mask that matches his current expression (as in, whenever his real expression changes, the mask falls off to reveal another one that reflects that.)

The first (and only) to have ever seen his face underneath the mask was a frog, who claims, "Kedamono's face... looks like his mother's." Kedamono seems to be the kindest and most caring of all characters, showing his concern every time someone was injured or when something was destroyed. Though if offered a chicken leg, he forgets his morals and will do almost anything to have it. He also appears to have an egotistical streak of his own—despite it not nearly rivaling Popee's—as he has unwisely goaded Popee on during shows of skill. Though his patience (especially concerning Popee) is considerable, he has several moments of bitterness and unwillingness to help Popee, possibly due to the foul treatment Popee tends to put him through.

Kedamono wears a mask because he's afraid of exposing his true nature, which is that of a "beast" (this may literally mean he's disguising himself as a human with his mask, and he's disguising his true nature as a wolf).
