What do you give a child who's got everything?

I love buying things for my friends' kids because I can buy them anything (toys, clothes, books, and so on) and there's always the visible excitement on their cute little faces. However, shopping for my nephew's birthday present is a bit of a nightmare. His parents are very wealthy and he has everything he could ever want. He isn't a brat, he's a lovely child who seems to appreciate presents but it always follows with "thank you so much, oh! I have one of these!" --all the time!

When he was 2 we bought him a small peddle car, made out of plastic kid-safe material only to found out that he had a custom made battery-rechargeable luxury "automobile" with comfy seats, large enough to fit in a 10 year old. When he was 3 we bought him a child's animal type of computer, you know those ones that you press the animal shapes and they make the animal sound? We were left embarrassed because we found out that he already had his own iPhone, iPad and Mac laptop with all the educational games already installed in them. On another occasion we decided to play it safe and bought him a book, and guess what? He already had it! It wasn't even a best seller, no, that would be too obvious. We bought a book we found at the very corner of the shelf, that wasn't even popular or anything. Bless his little heart, he said, "thank you aunty I love this book, I have one exactly like this!".

He is 5. I want to buy him something that will light up his face, any idea would be appreciated. Thanks so much!
