Signibble resembles a orange-yellow skinned small humanoid with prominent fangs, squinty eyes and a dual colored black and yellow hair. He wears a yellow kimono with black stripes, as well as a pair of sandals.
Signibble is a very mischievous Yo-kai, who prefers to having fun in crashing Nate's sleepover repeated times by manipulating the T.V.

Receiving food (favourite): "Yeahhhhh!"
Receiving food (normal): "Thanks!"
Receiving food (disliked): "What was that?"
Freed from the Crank-a-kai: "I'm OUT! I'm all charged up and ready to be friends with you!"
Befriended (Yo-kai Watch: Wibble Wobble): "You and me, we're on the same wavelength!"
Signibble first appears in EP006, in which causes the T.V to change channels automatically and ruining Nate and his friends' chances of watching the Next HarMEOWny late show. Jibanyan tries to fight him (with a vaccum cleaner), but Signibble has the vaccum cleaner to suck Whisper inside and disable him, allowing Signibble to escape.
His medal is shown in EP010 implying he gave his to Nate alongside Komajiro.
In EP027, Signibble was seen in Yo-kai-lifornia where he was among the Yo-kai waiting in line for the release of the Yo-kai Watch Model Zero.
Signibble's "random" nicknames in Yo-kai Watch 2 are: Sparky, Nicky, Noshwave, and Nibbles.
"Signibble" is a portmanteau of signal and nibble.
"Denpaku-kozō" is a portmanteau of denpa (電波, "electric wave", though also used to refer to mobile phone signals) and pakupaku (ぱくぱく, onomatopoeia for munching on something), with the ending kozō ("youngster").
"Ondívoro" translates as "that feeds on waves", similarly to words like "herbivore".
