Bugby, A.K.A. Experiment 128, is an illegal genetic experiment created by Jumba Jookiba. He is designed to turn people into harmless insects. Those turned into bugs can understand all other insects and arachnids; only Jumba's technology can reverse the process. His one true place is on a farm protecting farmers' crops by turning rocks into aphid-eating ladybugs.
He was activated by sprinklers. He turns Lilo into a ladybug, Stitch into an ant, Jumba into a stink bug, and Pleakley into a praying mantis. 128 was later reprogrammed by Jumba to only turn inanimate objects into insects.
Bugby is a small green, mosquito-like experiment with four purple eyes, four wings and six teal legs.
Bugby can fire a purple ray from his stinger that causes people hit to turn into bugs and giant insects hit to revert to the normal size of bugs. Anyone turned into a bug can communicate with all other insects and arachnids. When Bugby was reprogrammed, his ray caused rocks hit to turn into swarms of aphid-eating ladybugs.
The only way to reverse Bugby's effects is with a machine built by Jumba.
- Bugby's pod color is purple.
- Bugby is described by the experiment computer screen as, "Experiment 128. Primary function: Bug morpher. Turn civilizations into harmless insects".
- In his episode, Bugby's eyes are purple, but in Leroy & Stitch, they are black.
- Bugby is one of the few experiments to not appear in the group photo at the end of Leroy & Stitch.
