dollar stores are a great playground for hides water dishes ect.
I also get alot of silk plants from crafts stores and dollar stores (they cost half as much as the plastic ones at the pet stores). If you watch for deals you can get em cheap and they make the enclosures look much more realistic. Just be carefull which you get because alot of them have metal wire running through them and you would hate to poke one of your lil guys.
