Forehead

Forehead, A.K.A. Experiment 044, is an illegal genetic experiment created by Jumba Jookiba. He is designed to sing barbershop tunes annoyingly off-key. His one true place is with Mrs. Hasagawa as one of her "cats."

Bio
Experiment 044 was the 44th genetic experiment created by Jumba with Hämsterviel's funding. He was designed to agonize his victims with annoying off-key barbershop tunes.

044 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. 044's pod was one of the many experiment pods that landed in Mrs. Hasagawa's yard.

Lilo & Stitch: The Series
044's pod was found by Mrs. Hasagawa along with numerous other pods.

When Lilo and Stitch visited Mrs. Hasagawa, she, mistaking the experiment pods for apricots, offered them to Lilo and Stitch, but not before washing them and thus activating the experiments.

Lilo, Stitch, Jumba and Pleakley later captured 044 and the other experiments, but returned them to Mrs. Hasagawa when they saw how much she cared for them.

Leroy & Stitch
The first 624 experiments, including Forehead, 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 Forehead 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.
