Below is a list with examples of the types of toys chinchillas do enjoy.

Chew toys: bark bites, cholla chews, pumice stones, lava bites, chunnel chews, apple or pear twigs.
Apple and manzanita branches: Use large and small branches. Make sure they are organic with no pesticides added. They should be scrubbed in hot water, boiled and oven dried prior to giving them.
Grass mats and roll-a-nests: Grass mats work well for wire cages as a place to rest feet and give great chewing entertainment. Roll-a-nests are grass balls that come in a variety of shapes and sizes. Be careful if you live in a humid area. The wire can rust so always check the wire support inside the nest for rust. Discard if found.

PVC pipes: Use with caution if you have overzealous chewers. As long as your chinchilla doesn’t chew them, they can be a lot of fun for a chinchilla. If you do try them, just watch for chewing and remove if needed.
Ferret tubes: Holes can be drilled in them to attach to the side of the cage with wire. Chinchillas will use them to rest in and on.
Wheels: All chins love wheels. Recommended wheels include the 15 inch Chin Spin, (smaller wheels cause the chinchilla to arch its back unnaturally) the ED wheel, and the flying saucer.
Grapevine rings: These are untreated grape wreaths available at local craft stores like Michael's.
