My GCC won't go near a happy hut, but I found a little fleece blanket with a stuffed carrot head on top and hung it over his favorite sleeping spot. He loves it and climbs under it every night! As for toys, he loves balsa, curly straws, the shredding discs, the woven shreddable toys (but strangely will not touch the finger traps. Goofy bird!), vine foot toys, and foot toys with both acrylic and SS on them. He also loves the cat type balls with the bells in the middle, but those are a supervised toy only because he chews it to get the bell out when we aren't playing "fetch" with it. Those bells are pretty small and dangerous, so as soon as he gets a big enough hole, I throw it away and give him a new one.
He does have a rope perch, both a rope and a sisal boing, rope atom and rope round swings. Roma is not a big chewer, but I keep a close eye on the rope toys for fraying or chew spots.
Each bird is different. It has been a lot of experimenting and I continue to try to find new things he will play with.
