Papa Windbag appears as a ruddy old man with a big red nose and a long white beard that reaches to his feet, wearing a yellow striped robe and straw sandals. On top of his balding head there is an gilded fan with the word appare (天晴, meaning "splendid, magnificent") painted in red. His thumbs have a prominent generic fingerprint design.
While unchanged in the anime, games and other media, the text on his fan is edited to say "I RULE" in the English manga.
Papa Windbag has a brazen, boastful personality and passes it on to whoever he Inspirits. He appears to adhere to a personal code of honor and refuses to lie about his achievements, instead drawing the line at exaggerating them to make them sound more impressive.
Papa Windbag causes the possessed person to brag about their personal achievements and skills in a boastful manner, even if they're average and mundane.

Papa Windbag appears in EP033 where he Inspirits Bear, Eddie and Katie, making them boast about their mundane summer activities. Nate attempts to deal with him by summoning the Classic Yo-kai - Boyclops, Lady Longnek and Pallysol to counter his bragging in a competition. The contest quickly becomes increasingly ridiculous to the point where the Classic Yo-kai are clearly lying. Taking offense, Papa Windbag calls them out on it but becomes intimidated when they demand that he prove that they are lying. Papa Windbag concedes defeat, saying that he can only exaggerate but not lie.
Papa Windbag later appears in EP057, where Nate summons him to counteract the power of Cap'n Crash. While Cap'n Crash tries making Nate regret something, Papa Windbag makes Nate so self-congratulating that he spins it into a positive thing. However, when Cap'n Crash makes Nate choose a bad present, Nate becomes so regretful that even Papa Windbag's bragging powers become useless, causing Windbag to flee.
Papa Windbag has qualities that mark him as a non-literal tengu: a boastful, self-inflated personality and topped with having a prominent ruddy nose.
