What items to go in a castle?

[attheendoftheday]

A question for a friend. She is getting her DS this castle for christmas, but what other bits and pieces will she need to go with it? She is getting some figures, but do you get furniture to go with toy castles? If so, where from?

One of my boys favourite accessories is a battering ram siege tower, it is on wheels and has a swinging battering ram to knock down walls. I am fairly certain it came from the ELC but that would have been 5 years ago now.

We also got a big plastic floor mat again from ELC for it to go on - cost a fiver at the time and well worth it.

Have a fairly good catapault too that throws balls over the castle wall, no idea where that came from though.

Thanks for the tips. Is the Kidkraft castle particularly good?
