>>7502509Ninjago City and the new Destiny's Bounty seem too easy, so I'm going with the first Dojo. That was back when I actually still played with sets and didn't just use them for parts and it was the first big Ninjago set I got. Plus Nuckal was awesome.
Another one that's just special to me is the first Cole spinner I got on christmas when I didn't even know Ninjago was in stores yet (I think my parents got it like one or two days before christmas)
