Papi always disapproved of young Kronk's culinary interests and wished that Kronk instead would settle down with a wife, have kids and live in a large house on a hill. He is very strict, but ultimately wants his son to have a good life.
In the end, Papi learns to accept Kronk for who he is, finally giving him a thumbs up.
Though he has few appearances in the sequel, Papi is instrumental to the plot of the film as Kronk is always trying to get Papi's approval. Papi arrives at Mudka's Meat Hut and confusion ensues as several of Kronk's supportive friends try to pass themselves off as Kronk's wife and kids. But in the end Kronk realizes that his wealth is in his friendships, and this finally wins his father's thumbs up and Miss Birdwell's love.
Papi makes a few guest appearance in the series, first appearing in "Clash of the Families" in the national celebration "Famaolimpics". Since Malina promised she would dance with the winner, Kuzco switches families between Pacha's and Kronk's.
He also appears in Kronkenitza where he tells Kronk where their family comes from.
