Wizard & Wizard shuttle suggstions

[Frank_Stein]

What about the luggage from discworld? That'd be cool.

I was thinking of something along those lines as a possibility, but would it be a mob or what?

Something that looks like an ordinary bag but bites people's arms off who try to rifle through it would be funny.

Maybe it stands still until you recall it, then it scuttles to where you are?
