Instructions
Pull off the legs and head pieces from the LEGO figure.
Attach a 2-by-2 brick to the top of the legs.
Attach a 2-by-4 brick on top of the 2-by-2 brick, and two 2-by-6 bricks evenly on top of that.
Add two 2-by-3 bricks to the sides of the 2-by-6 brick so that they cover one section on both ends and leave a 2-by-2 portion hanging over the sides. This will leave a 2-by-4 section in the middle which must be filled by a 2-by-4 brick.
Attach two 2-by-4 bricks on either side of this section so that a 2-by-2 portion is left in the middle. Attach the head here, and place it in the middle of the four notches so that it is secure.
Attach the two 2-by-8 bricks under the overhanging 2-by-3 bricks so that they stick outward like arms.
Attach under both arm bricks a 2-by-4 brick in the middle to provide girth. Attach a 2-by-2 brick under the remaining space on the front of the arms so two notches are attached to give the LEGO Tank fists.
