Leave it to Kero! (2000)

Following the events of Cardcaptor Sakura Movie 2: The Sealed Card, Kero and Spinel share a plate of takoyaki (octopus balls). They get into a fight over who gets the last piece, and in the process send it flying out the window. They both chase the takoyaki, and each other, in a mighty effort to be the "takoyaki captor".
