Jen is the assistant of Andy at the National Museum. She also works with her boss Mrs Pickles and the Janitor.

Jen usually helps Andy to set up an exhibit but when something gets damaged, Andy asks her try to fix it, while he disappears. Jen doesn't realise he is traveling back in time to replace the thing that was damaged. Andy then returns and Jen helps him fix the exhibit just in time before Mrs Pickles arrives.
