"Laser Light Cannon"
Steven and Greg find and retrieve the Laser Light Cannon from deep within Greg's storage unit.

"Maximum Capacity"
Steven, Greg, and Amethyst try and clean out the storage unit, but the latter two end up watching Li'l Butler the whole time and become addicted to the show once again. Later, with the help of Pearl and Garnet the entire unit is cleaned out, with most items being transferred to Amethyst's Room.
