Lilly is the only female member of the Umi-Clones. She's Milli’s evil clone.
Lilly was created by some hairs from Milli that were collected overtime by the Troublemakers. Lilly is considered as the brains of the Umi-Clones.
Due to a flaw in the cloning process, Lilly has some slight differences from Milli. Her dress is purple and has a lily pattern on it, instead of a pink dress with a daisy pattern on it.
