==Appearance==
==Anime==
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 Toiletta 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.
