Natural perches are good, you can make your own out of birdsafe woods like willow. One of my most common google searches I make is "is xxx safe for parrots", it works every time
If you get rope perches get the natural fibre type not the brightly coloured synthetic ones which can cause problems if the fibres get stuck in a birds gullet.
You can buy expensive cozies for your birds to snuggle up to at night but a bit of fleece cut from some unwanted clothing is just as good.
Casper's toy of preference at the moment is an empty plastic water bottle which he chases around the room and throws about. Just use a bottle that is about the same size as your bird.
