My suggestion would be to simply get a small locking case -- available at any hardware store or office supply store -- and keep your obvious toys out of reach. If asked, say it's for financial documents -- checking statements, W-2s, pay stubs, things like that. Best cover is plain sight, no one will give a rats behind about that sort of stuff, and tucking it under your bed won't seem too strange.

Otherwise, hairbrushes have a lot of promise if you can find ones with nice handles, zip ties, scarves, screwdrivers, or bottles.

...mind you, I do love the the idea of someone 'popping it in their mouth'...
