I just rediscovered this joy the other day, and I spent the day driving around & listening to my favorite music while hunting these down at various stores. I definitely recommend engaging with a childhood interest again if you can; it brought me such a pure and simple form of joy that I haven't felt in a while. I guess I thought I was too old to be doing this and that I had to spend my money on practical stuff, but then I remembered we're all just here on the planet to have fun. Any sort of little mission I can go on with an objective to locate something is always fun to me as well. I felt like I was on a quest to various Targets & Walmarts. People online have also cracked the product codes so you CAN figure out which pet you're getting if you don't want to waste your money, but the surprise is super fun as well. They're super cheap, like $3-$4 a piece. The search for them was the most fun part, but looking at them on my windowsill is also very cute.
