Stitch and Yuna are sucked into an alternate universe by Experiment 272/Wormhole and meet a bad Stitch with a jetpack who enjoys destroying an abandoned city, along with alternate versions of Jumba, Pleakley, and Gantu. As Yuna tries to convince the alternate universe's 626 that ʻohana is better than destroying things, the Jumba of Yuna and Stitch's universe tells them via her good deed tracker communicator that they only have a limited time to find the interdimensional portal back home or they'll be stuck in the alternate universe. However, only Wormhole knows where the portal is and he refuses to leave until he finds a slipper belonging to Jumba that he lost to a previous portal before, which he believes to be in this alternate universe.

After finding out that Tigerlily is afraid of lightning, Stitch and Yuna chase a cloud to try and capture Raijin's son, also named Raijin, from it, but he's small and not very scary. Stitch tries to scare Yuna's cousin again but fails, and so does the yokai, so Jumba creates an electric energy drink using Sparky's electricity, which Stitch uses to temporarily gain electricity powers.
