Tornado

 is a Tier 5 Tank that upgrades from Octo Tank at level 60.

Design
The looks similar to the Octo Tank but with 2 more barrels added around its body. It now has so many barrels they overlap, so every other barrel is layered beneath its neighbors. The tank resembles a Penta Tank (in the same vein as Quad Tank) with another, reversed Penta Tank layered below it.
