Stitch & Ai S01E10 - Dream On

The Woolagongs send an agent down to knock out and capture Stitch. His dream beam gun instead zaps Ai, bringing her imaginary friend, Cheng Fei, to life. Cheng Fei takes her to a mythical land in the mountains called the Valley of Dreams, which brings Ai's dreams, good and bad, to life, including a dream of Stitch growing into a monster. Meanwhile, Jumba creates a mo, and Stitch captures the agent that zapped Ai. After Jeijei contacts Jumba saying that Ai was absent from school, the aliens set out to find the little girl.
