Mr. Stenchy

Mr. Stenchy, A.K.A. Experiment 254, is an illegal genetic experiment created by Jumba Jookiba. He is designed to use his cuteness to get people to take him home, where he emits a noxious odour. His one true place is on "Plorgonar" Pleakley's home planet. Mr.Stenchy is voiced by Frank Welker.

Bio
Experiment 254 was the 254th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to use his cuteness to smitten Jumba's enemies into taking him back to their headquarters, where 254 would emit a noxious odor that would make the area uninhabitable for decades.

254 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.

At an unknown point after this, Experiment 254 was activated.

Lilo & Stitch: The Series
An estimated 12 hours after his activation, 254 was captured by Lilo and Stitch, and taken back to the house. Lilo fell for 254's cuteness, and decided to keep the newly-christened Mr. Stenchy, despite Jumba's warnings.

Lilo began taking Mr. Stenchy to Mertle's tea parties in an attempt for the former to be accepted into their group.

However, when Stitch was left home alone with Mr. Stenchy and Gantu attacked, the former allowed Gantu to take Mr. Stenchy so that Stitch would be rid of them both.

However, back at Gantu's ship, Gantu also fell for Mr. Stenchy charm before he could teleport the latter to Hämsterviel]].

Thus, Gantu began to grow attached to Mr. Stenchy until Lilo and Stitch arrived to take Mr. Stenchy back. Due to Stitch abandoning him, Mr. Stenchy chose Gantu. However, Mr. Stenchy began to emit his stink, forcing Gantu to hand the latter over. Mr. Stenchy was then sent to Plorgonar, where he could be loved in spite of his smell.

Leroy & Stitch
Mr. Stenchy reappeared, inexplicably back on Earth and not producing his deadly stink, suggesting it wears off after a while.

The first 624 experiments, including Mr. Stenchy, 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.

It is unknown whether or not Mr. Stenchy participated in the following battle between the experiment 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.
