Nintendo switch hardware Nintendo laboratory Variety Kit

Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.

We make pianos, fishing rods, motorcycles, etc. out of cardboard, and combine them with the Nintendo Switch to create various "games" such as playing music, fishing, racing, etc. We make and play by ourselves. We know how it works and we are absorbed in it, and we come up with a "new game" without realizing it.
This is the "Nintendo laboratory".
What kind of "games" would you invent?
