Janna Jookiba is a genetic experiment of Jumba's, designed to take care of the other experiments and to blend in with humans by looking exactly like one. Due to being a creation of Jumba, she is often cited as his daughter. She masquerades as Jumba and Pleakley's daughter and the cousin of Lilo and Nani.
Janna is an alien genetic experiment, but she looks like a normal human: a Native Islander with brown skin, dark eyes, and curly black hair. She normally wears a space jumpsuit with pockets that hold various tools, and keeps her hair in a tight bun. She sometimes wears shorts, a Hawaiian shirt, and lets her hair down.
