If there is a place in your house where stuff is kept in boxes (for example; our laundry room has tons of boxes with crap that no one cares about.) you could try stashing it in multiple of those; try hiding them in any baby toys, if you still have them. Or you could possibly you could hide where the garbage is kept: for example, if you have a mini trash can in your room, you could dump out all your candy UNDER the bag, then put the bag on top of it again. You could also do this with other trash cans. (Just remember to clean out the trash can first.)
so there are some ideas, hope they meet your approval, and good luck!
