Dr Ice Cream is first seen in the episode “The Duke of Nuts”, helping Princess Bubblegum overcome her problem with being green and bald (done by a liquid she suspected was thrown by the Duke of Nuts, but really it was done by Finn by mistake.), so she puts her in a “medicinal milk suit” and says she’ll be tip top in her beautiful self within five days. She also puts on an annoyed look when Jake laughs at the Princess’ current state. She later appeared in “Mystery Train” as one of the last passengers to be murdered. Somehow, she also appears in “Mortal Recoil” to recover Princess Bubblegum from her deathly situation.
