Babblong appears as a yellow-skinned, grinning Yo-kai with a massive, beak-like nose, hanging down to his chest's height. He has greenish-blue feather-like hair, with a tail going down to the small of his back. He wears a light purple sash around his waist and a blue skirt, and a pair of sandals.
He speaks with a thick Kansai accent. As expected, his stories are what's most important to him. When possessed by Wazzat, he says "What's the point of social interaction if you can't make people listen to you, y'know, y'know?".
He makes people tell stories until they get tired. These stories are usually boring and are often about an unknown uncle. It is likely that many of these stories are actually from Babblong, and that he really makes people tell the stories for him. When Babblong possess someone, they start speaking with an Osaka accent.
Yo-kai Watch animation series
In the anime, Babblong first appeared in EP015, Inspiriting people at Springdale Elementary. Nate attempted to summon Jibanyan but ended up Inspirited by Babblong, preventing him from finishing the summon. Jibanyan, having been alerted to the Summon, eventually got fed up waiting for Nate to finish and ran to school all the way from Nate's house, sending Babblong flying in one hit. Nate was finally able to summon Wazzat to stop Babblong’s constant chitchatting. In defeat, Babblong walked away. The next morning, Nate and Whisper encountered Babblong again, once again telling boring stories, much to Nate’s dismay.
Nate first summoned Babblong in EP021, who expressed pleasant surprise at being summoned. Babblong was asked to stop D'wanna from Inspiriting Katie, who had been abandoning activities with her friends as a result of D'wanna's influence. Babblong engaged D'wanna in an Inspiriting battle, causing Katie to switch between lethargic and talkative states constantly until D'wanna keeled over in exhaustion.
In EP027, Babblong was seen in Yo-kai-lifornia where he was among the Yo-kai standing in line waiting for the release of the Yo-kai Watch Model Zero.
In Yo-kai Watch, non-hostile Babblongs can be found all over Springdale who provide advice on the game's mechanics. When talked to, each Babblong warns the player that its explanation is lengthy, and expresses annoyance should the player choose to decline its offer.
Babblong is also the antagonist in the request Talk Like the Wind, where he is inspirting a worker at the Gourd Pound Museum. After confronting the big nosed Yo-kai, he admitted he did so because he wanted a friend, and the players can become friends with him.

"Nagabana" translates as "long nose" (Japanese: 長鼻,Nagabana). It's also a pun on nagabanashi (Japanese: 長話,nagabanashi Tr: rambling, long conversation). It may also be partially based on banana, given the banana motif of his post-summoning background in the anime. "Babblong" is a portmanteau of the words babble or babbling, and long. It may also be a play on the term babble on.
