Maybe that last one was just for kids with slight OCD, like me.
Anyway, Kinder Eggs remind me of everything awesome about childhood, and I buy one time to time at a local Russian/Euro Deli store. Every Russian store I've been to sells them, so you should give it a try.
Sadly, those toys are nowhere near as amusing as they were when I was a kid. Oh well, nostalgia (and chocolate) are still delicious.
