Christmas gift for boyfriend?

My boyfriend said he wants to learn how to play the ukulele. So I was thinking I could teach him basics with mine and get him a ukulele for Christmas. But just a ukulele? I feel like I should get him more but i have no idea what. He has a lot of pets so he is an animal lover. He likes meme. He likes music. He is smart. He likes to skateboard and beanies. He also likes shirts with pockets and longsleeves. He also smokes weed but I dont know if I wanna encourage that.
