Robin, a girl?

Yes. In Beverly Hills Ninja, Robin plays Gobei, the ninja who was assigned to protect Haru, the "Great White Ninja", played by Chris Farley.

In one scene, Robin dressed as lady in disguised so Haru wouldn't recognize Gobei sitting across from him in a restaurant.

A fan asked Robin:

"What was it like to work with Chris Farley?"

And here Robin's answer:

"He was fantastic"

Plot Summery
Following a ship wreck, a baby is rescued by a clan of Ninja warriors and raised by them as one of their own. But Haru, as he is called, never quite fits in, nor does he manage to make a worthy Ninja. However, the good-natured and persevering Haru, in his own bumbling way, and with some help from Gobei, manages to prove himself to be a winner in the end
