The Jungle Tarantula guards its BattleCave with its hairy legs and poisonous green-yellow color. It is pretty nasty looking and just waiting for someone to approach. If you get too close, it unleashes a large orb from the chute at the attackers. There's a trapdoor hidden under vines on the roof of the BattleCave. Mean!
Can be stacked and placed with other BattleCaves to form large fortresses.
Each wall can be individually replaced, to reconfigure the cube.
The World Crystal is attached to a revolving door and can thus be saved at the last second.
The large orb can be unleashed on enemies via the roller conveyor.
Any intruders will fall through the well-camouflaged liana trapdoor from above.
