|Introduced in||"Blood Under the Skin"|
The Red-faced Monsterappears in "Blood Under the Skin." Crying she picks up Finn and thinks he's her baby after Finn runs out of the Swamp of Embarrassment with a red face. She tries to get Finn to nurse, which he emphatically refuses. Jake manages to sneak Finn out of the monster's grip. She may be a type of yeti. No one truly knows why she was crying, but it is probably because she lost her baby. Her baby is never revealed in any episodes so far.
Red-Faced Monster is similar to a yeti with a white fur and a red face.
