This is one of slycooper2020s' suggestions, which is Mickey outgrowing the universe, so here it is.
--
Mickey and Minnie are taking a stroll and then all of a sudden, a mysterious shady figure shoots Mickey with his growth ray as the laser hits him. Minnie asked Mickey if he's okay, but he told her that he's feeling woozy. Then, the growth sequence started as Mickey was shocked that everything's small as Minnie told him that he's growing. Mickey then shouted Minnie's name as he reaches the sky while he grows bigger.
