Grumples

Grumples(しわくちゃん) is a Bukimi-class, absorption attribute Yo-Kai ranked B

Appearance
Grumples resembles a rather elderly woman with wrinkled skin, sulken eyes and only two teeth on her upper mouth. She wears a ragged old cloak which is patched in some areas, accompanied with a green sash. She carries a wooden staff with a ghoulish face in the top.

Personality
Matching her elderly appearance, she behaves like an old woman: she has a lot of trouble hearing Nathan's complaints about her powers and acts showing signs of senilism.

Abilities and Powers
Grumples has the ability of shrivel everything she fires at with a beam from her staff. When used on humans or other Yo-Kai, she can age them significantly. The effects dispel with washing on the sink.

History
Grumples appears in episode 69, when she is revealed to be responsible for the shrivelling of Nathan's school paper. Nathan complains, to no avail, since Grumples has severe hearing problems, instead using her power to shrivel Nathan's clothing and even aging Nathan and Whisper and forcing them to use the sink to dispel her effects. Hanako-san appears and puts Grumples and the others into a training regime which works to the point that Grumples rejuvenated into Everfore. The female Yo-Kai gives Nathan her Yo-Kai Medal out of gratitude; however, not too long after that, she sneezed and turns back into Grumples, which starts firing her beams everywhere.

Origin
Given that Grumples evolves with the application of face-powder, she might be partially inspired by the oshiroi babaa ("face-powder hag"), a ghostly old woman who serves a god of cosmetics, bringing him sake to warm him in the coldest days of winter, and constantly applies face powder on herself because she's ashamed of her aged, wrinkled features.
