The Las Vegas Museum of Natural History brings Brett and Wayde in to create a new interactive exhibit: an aquarium in the shape of a carousel, but instead of horses this carousel will be filled with seahorses!

Brett and Wayde revisit some of the most unthinkable items the ATM crew has turned into tanks over the years. They share never before seen footage that documents the challenge of creating some of the most unconventional tanks.

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.
