Visitor to Houston

I’m from the upper Midwest (ND/MN area), and I love collecting books, comic books, blind boxes (think unicorno, Pokémon, etc), and crafting. Where do I need to go while I’m in the area? Shops, malls, restaurants. I’m open to anything. Already planning to do the touristy stuff, natural science museum, zoo, aquarium, etc. I’m here for a week. Headed down to Galveston for the afternoon today.
