New ball owner (2.5 years old, female).

The tank I acquired has one half log "hide", a smallish waterdish (6"x6"? and a branch.

I'd like to get her more stuff to be in, on and around. The pet store plastic crap is boring. Is there anything I shouldn't put in there (i.e. cedar I know)? For example, will she react poorly to leather, plastic, resin, plaster, etc?
