Bloom, A.K.A. Experiment 404, is an illegal genetic experiment created by Jumba Jookiba. She is designed to disable enemy vehicles. His one true place is at a greenhouse.
Experiment 404 was the 404th genetic experiment created by Jumba with Hämsterviel's funding. She was designed to disable enemy vehicles (does so by shooting large seedpods from his arm like appendages where upon impact the seedpods explode with life, The plant that grows then constricts and tightens around the target causing the target to be crushed and destroyed.).
404 and the other first 624 experiments were deactivated and smuggled to Earth by Jumba during his mission to capture Experiment 626.
All of the experiment pods were released and scattered across the island of Kauai.
