|| Lilo and Stitch try to help Mrs. Hasagawa out by organizing her fruit stand and cleaning her yard. However, when she tries to offer them a bowl of apricots for their help, they discover that the bowl is actually full of experiment pods, and her house is later full of stray experiments, which she believes are "cats". Lilo and Stitch try to gather all the experiments, but it turns out that Mrs. Hasagawa has taken a liking to them and tamed them herself, so the experiments won't need to be captured after all.
|| The leader of the Evil Genius Organization (E.G.O.) believes that Jumba has turned good and wants to revoke his membership, but Lilo and Stitch convince him to visit Earth so they can prove to him that Jumba is still worthy of membership. As they construct an elaborate facade to trick him, however, a failed non-evil experiment is activated. Meanwhile, 625 and Gantu are playing go fish when they hear about this experiment. After learning that said experiment has no evil traits, they conclude that Hämsterviel would have no use for it, so they continue their card game.
