SFS, A.K.A. Experiment 263, is an illegal genetic experiment created by Jumba Jookiba. She is designed to have a brain like a smart file system.
Experiment 263 was the 263rd genetic experiment created by Jumba with Hämsterviel's funding. She was designed to have a brain like a smart file system.
263 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.
SFS is a non-speaking, purple Stitch (626)-like experiment with a large bump on her head where her brain/data is stored. On Earth a smart file system is not that much data. However, on Jumba's planet, a Smart File System is nine hundred and ninety-nine Ducentillion Yottabytes.
- Ducentillion is a number with 603 zero's after it.
- Her name (SFS) is the abbreviated form of "Smart File System".
