"PJ" is the forty-seventh episode of Lilo & Stitch: The Series. It aired on April 22, 2005.
When Lilo is blamed for pranking her strict substitute hula teacher, she decides to use a practical-jokester experiment to get revenge and impress Mertle. Stitch must stop them before the jokes go too far.
- Moral: Playing jokes can be fun, but only if the other person is laughing.
- Stitch somehow woke up on his own while under Drowsy's effects, possibly indicating that other experiments are not affected as much.
- Gantu, Reuben and Hämsterviel do not appear in this episode.
