"The second set that I designed. When we decided upon the theme of Sky Pirates, I knew that this was the perfect opportunity to make a land-based set that can't fly. Graphic Designer Dano made some awesome flag decorations, which play homage to the classic Islander sets, but with a spider twist."
- This is the first Ninjago set to feature a big figure, Dogshank, who is exclusive to this set.
- This and 70642 Killow vs. Samurai X are the only two Ninjago sets to include a big figure.

- This is one of two sets to include Cole in his ghost form, the other being 70593 The Green NRG Dragon.
