2 Works in Kaeloo (Cartoon)
A cat on the run from his old home encounters a portal to a new world... a strange world inhabited by an indestructible duck, a manic squirrel, and a split-personality frog who want him to join them in a game of hot potato. Maybe he was a bit too hasty in destroying that portal... Origin story of sorts obviously, with some light Mr. Cat/Kaeloo.
They could have fixed some things, that day. Kaeloo could have trusted Mr Cat, Mr Chat could have disregarded her rejection, Stumpy could have been more serious, more present, and Quack Quack could have helped them. But they did not do it - and that's great, because the big changes are always preceded by a tragedy.
