This one was a very tricky reader poll to answer; I would have gone for 'All of the Above (except nothing)' if it were an option. Games/Toys was my first choice, with Dust a close second. :) But I've also got some books under there, and some miscellaneous stuff that there was no better place for, and probably some mystery stuff that's been lost under there.

P.S. No monsters under the bed?
