2509 Earth Dragon Defence is a 227 piece Ninjago set that was released in August 2011. It includes Cole, a brown and green dragon, and Wyplash. The dragon is very large and has four legs and spikes. It includes a shooting function similar to the ice dragon's and a function where you can swing its tail to fire a boulder at the skeleton. It also contains some crystals and the Scythe of Quakes. The Earth dragon's head has a different mould than the other dragon's heads.
- The Earth Dragon appears in LEGO Battles: Ninjago in the Skullkin story and "Goliath" game mode.
- In Ninjago: Masters of Spinjitzu, the dragon included in this set is named "Rocky", by Cole.
- Rocky is depicted as a wingless flightless dragon in the set but in the TV Series he has wings and is able to fly like the other 3 dragons.
