Collect Them All
When I was 10-11ish, I really loved my little pony. And there was an app on the app store for equestria girls (an MLP spinoff), where you did quests and stuff. Well, to complete the quests you often needed help from MLP characters. The way that you got their help was either by scanning a doll, or using gems. You had to pay for gems, and only got them for free rarely.
I had no Equestria Girls dolls, so this really sucked for me. Until I thought, “Hang on, what’s stopping people from just going to the store and scanning dolls?” which then led me to realizing that I could just look up pictures online and scan them. It ended up working, and I was so proud I bragged to my mom about it for ages.
