Jennifer is Gadget Girl's portable console that she uses to watch Miss Madson and track everything that she's been doing.

She can also help Gadget Girl on her quest and alert her when something bad his happening.

She also has many other uses as well. Such as showing a map of different places, scanning food for anything suspicious in it, and even to video chat with friends!

She's extremely smart and can help us solve any difficult puzzle that we run into.
