Sproing is a dark navy blue and white koala-like experiment. She vaguely resembles Stitch with a coiled, spring-like body, a large white patch on her face, a wide mouth, red round nose, large, dark eyes, two small ears and antennae. She stands 2 feet (when her spring is coiled) and weighs around 15 lbs.
Powers and abilities
Sproing can launch boulders by using her spring-like body, bounce and jump really high. She is able to hold heavy weights with her strong coils.
Experiment 249 was the 249th genetic experiment created by Jumba with Hämsterviel's funding. She was designed to launch boulders. 249 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 some point, 249 was presumably activated, captured, and named Sproing.
Sproing was seen when Lilo was making her rounds with Scrump to check on all of the experiments, and she finished up near the movies, where Sproing was elevating a man who was changing the letters on the display outside the theater.
Later, the first 624 experiments, including Sproing, were rounded 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
Sproing participated in the following battle between the experiments and the Leroy clones by trapping Leroys in her coils.
However, 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 ʻOe", which caused the Leroy army to shut down due to the original Leroy's fail-safe.
- Sproing's pod color is green.
- Sproing is one of the few experiments who does not appear in the group photo at the end of Leroy & Stitch.
