Sprout



Sprout, A.K.A. Experiment 509, is an illegal genetic experiment created by Jumba Jookiba. He is designed to grow into a killer forest. His one true place is atop the pineapple water tower. Sprout  is voiced by Frank Welker.

Bio
Experiment 509 was the 509th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to spawn an uncontrollable forest of destructive replicas of himself.

509 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.

Lilo & Stitch: The Series
509's pod eventually made its way into a post office, where it was found by Lilo and taken home.

Jumba, unwilling to risk activating 509 due to the destruction the latter would create, locked the pod away.

However, Lilo and Stitch stole 509's pod the following night. Lilo then activated the experiment, named him Sprout, transplanted him, and fed him super-fertilizer.

The next day, Lilo took a rapidly growing Sprout to an orchid competition. When Mertle Edmonds approached Sprout and noticed he was not an orchid, Sprout lashed out at her, causing Mertle to accidentally break his pot open.

Sprout then grew into a massive forest of killer plants which took over the Kokaua Town fair, causing widespread panic.

However, Stitch was able to lasso the original Sprout and drag him into a pineapple-shaped water tower, trapping the latter and causing the forest to die off without the original Sprout.

This might have not been Sprout's actual one true place, but it was the best Lilo and Stitch could do on short notice.

Leroy & Stitch
The first 624 experiments, including Sprout, were round up by Leroy and taken to a stadium to be destroyed. However, Lilo, Stitch, Jumba, Pleakley, Reuben and Gantu arrived before the experiments could be destroyed.

Sprout participated in the following battle between the experiments and the Leroy clones.

The Leroys soon gained the upper hand in the battle, but were defeated when Lilo, Stitch, Reuben and several other experiments performed the song Aloha `Oe, which caused the Leroy army to shut down due to the original Leroy's failsafe. Sprout joins them for the song by playing the drums.

Stitch! anime
Sprout has made one appearance in the Stitch! anime and was mentioned in another. Though he did not officially appear in the second episode, his "offspring" did. It is revealed that Sprout can produce seed pods and launch them into space, where they cling to asteroids. One of these pods landed on the island and grew into a "Sproutling" (509-A) that carried out Sprout's original programming before being neutralized.

Trivia

 * Sprout is an obvious parody of Audrey II from Little Shop of Horrors.
