>>11288333OP here. Actually fellow anon they're found in a standard joy egg. There is no indication it's a JW dinosaur I just told my dad to buy me and my sister current some sort of Kinder Surprise edition for girls but instead bought us Joy. After we opened them there were dinosaurs and we're hooked since. I don't plan on stopping buying them but I don't care if I don't get single one of them.
Mosasaurus, the latest one from my edition.
