|Ninjago Battle Arena|
The arena itself is a large piece of moulded black plastic featuring no studs or other LEGO-compatible mechanisms. It consists of an irregularly-walled, roughly circular play area with four "dugout" areas for players to play from. The dugouts contain slots for a player's minifigure, spinner and cards plus a small bucket for weapons. The floor of the arena sports a holographic, motion-animated image. The Sensei Wu figure included with the set comes with a spinner and a single weapon - a golden staff - but no cards.
