What did you enjoy as a kid? Wanna recreate those things for my partner

What activity/thing did you enjoy and would love to have it back or experience again? It can be anything from a toy, to building forts (this was mine), going to an adventure park, playing something outside. Anything that made you happy as a kid.

Context: when he was little (5-15 y.o ), my partner spent most of his childhood in house, watching sports, but not experimenting, playing, making friends, socializing or trying new things. We are grown ups.

I want to help him out and recreate some activities/moments that are incredible for a kid so he can experience them and evolve through them. He is the type of guy that will enjoy little things (puzzles, legos), especially if he never experienced them before.

For example, he didn’t know how to ride the bike - so we rented a bike in our last holiday and went to the park. He had so much fun trying to learn even if his balance was bad because he didn’t experienced working with it at all during childhood.
