The snow monsters appear in "Prisoners of Love." Using his Ice Powers, Ice King creates them to beat up Finn and Jake after they disrespect his territory by crashing in front of his castle while sledding. Finn and Jake easily defeat the monsters (since they are made of snow), infuriating Ice King even more. Ice King can create them whenever he is near snow and is wearing his crown. Two of them appear in Righteous Quest 2.
