Jumbelina has eyes, pink lips, a nose, and two moles that are usually mixed up. She has her hair tied almost to the end from behind, wears a pink kimono with a beige long skirt and blue pants worn underneath.
Jumbelina has the ability to swap faces between two people or Yo-Kai, although she can't swap a face if she doesn't know its current location. In the manga she can mainly move facial features and she can also remove a face fully.
Yo-kai Watch Animation series
Jumbelina appears in EP052, having swapped the faces of Jibanyan and Whisper. At Nate's request, she swaps them back, but gets carried away and gives Nate the face of Lily Adams, who gains the face of Bear instead. After she finds herself unable to swap Nate's face back, Jumbelina diagnoses Nate's face as having run away in protest after Nate neglected to wash it too many times. Jumbelina agrees to help Nate get his face back, providing him with a bug-catching net she ordered online, and swaps in various replacement faces from other Yo-Kai for Nate.
The group eventually manage to find Nate's face by luring it out with food, having changed places with Dandoodle's face. Nate's face decides not to be a dog's face and tries to bargain with Nate, only to find that Nate now enjoys the attention he's receiving as a result of having Dandoodle's handsome face.
