There are many items Chase loves. The easiest way to get a gift for him would be to plant two or three Orange Trees in Spring. If you planted them soon enough they will be fully grown by Summer. You can collect two Oranges from each tree per day. Take those Oranges and cook them in a Mixer to make Orange Juice. He loves that and if you save the extras you'll have plenty left over when Summer ends and you can't get Oranges anymore.
