Cheeksqueek has a pink, peach-shaped head with rosy cheek marks and a single swirl of hair on top. His eyes are squinted and he has two tiny nostrils. He wears a light brown bib with the he (へ) character on it, and a pair of baggy green pants with darker vertical stripes. His limbs are proportionally thick to the rest of his body.
Cheeksqueek is a mischievous Yo-kai whose uncouth pranks and habits garner him the dislike of others.
Cheeksqueek can make people gassy by spraying an orange mist from his mouth. He can even propel himself by means of his own flatulences.
Cheeksqueek appears in the Shopping Street Narrows (Shopper's Row).
Befriended: "Let's be--*toot* ... Oh, sorry about that."
Receiving food (favourite): "Pbbbt! Good!"
Receiving food (neutral): "Pfft... average."
Receiving food (disliked): "Pbbbt! Nasty!"
Cheeksqueek first appears in EP012, in which he uses his power on Katie, much to her embarrassment. Upon being confronted by Nate, Cheeksqueek switches target to him, making him fart multiple times despite his earnest attempts to dissimulate it. Chasing him to the school's roof, Nate first summons Jibanyan, but Cheeksqueek is quick to inflict him with the same misery. He then summons Robonyan, who first tries silencing the sound, then changes the smell to roses, sending it Cheeksqueek's way. He finally stuffs a roasted sweet potato in his mouth (a food known to give gas when eaten in excess) to cause him the same embarrassment he's been inflicting on others. Having been put to shame, Cheeksqueek gives Nate his Yo-kai Medal.
He also appears in EP091 to perform on the song battle but when Whisper proposes to form a group with Cheeksqueek, he refuses with a spray of his gas.
Onarazumono" is a combination of onara (おなら, "fart") and narazumono (ならず者, "scamp, ruffian"). "Cheeksqueek" is a portmanteau of the words cheek, and a corruption of the word squeak.
In Spanish, "Cuesco" is a corruption of the phrase Que asco ("That's gross")
In German, it means Fart with an i at the end.
Cheeksqueek could be based on the Okkeruipe, a youkai of Ainu origins that plays rude pranks on humans by emitting powerful flatulences. The only way to make this creature go away is to answer in kind, or to imitate the sound with a hand over one's mouth. Its true appearance is that of a small black fox.
