A business communications company is in need of an interactive aquarium shaped like a giant telephone. With The General left in charge of the office, things get rough around ATM, and the staff still have to build a tank that is used as a dog house.

Brett and Wayde are hungry to create two restaurant tanks. The Salt Life Food Shack wants the guys to bring the ocean to life with a pipeline wave tank, a new shape for ATM. Home in Vegas the guys create a smoker tank for The Rolling Smoke BBQ.

In this Character Favorites special, six of ATM's employees Brett, Wayde, Heather, Agnes, Redneck, and the General take a walk down memory lane with each of their most favorite tanks.
