It would take a bit of work to make RQ water resistant, but a built in squirt gun for defense against puppies could be fun. Sealing off the PCB's would be fairly simple, just brush on some acrylic or epoxy paint. The extreme PC cooling guys have been doing that kind of thing for years to protect against condensation and leaks. Not entirely sure how to seal up the motors though.
Another option could be Silly String or a variant thereof. Like the Spiderman kids toys that strap onto the wrist and shoot "webbing". No need to waterproof the robot then.
Took me a little bit to think up something that wouldn't fall under cruelty rules. First thought was a taser...
Watch out, don't step in the anthropomorphization.
