BooGoo

ブーグー

A small, mysterious, purple alien resembling an insect, jellyfish, or octopus, possessing shapeshifting abilities. She is friendly toward others but is mean only to Stitch, whom she frequently harasses and steals food from, deeply angering him since he loves to eat. Hämsterviel discovered her while incarcerated on a Galactic Prison planet; he brainwashed her and sent her to Earth disguised as a fruit fly to break Stitch's good deed counter (where points decrease for good deeds and increase for bad ones). Jumba found her while repairing the counter and removed her brainwashing. She subsequently became Pleakley's pet, who named her "BooGoo" because she can only say, "Boo goo!" She rarely displays her shapeshifting ability; she actually shapeshifted only in her debut episode (episode 27) and in episode 41, when she turned into a parachute to save Yuna, Jumba, and Pleakley.
