The inside looks like a regular toy store. It has rows of shelves with toys in them. SpongeBob and Patrick got intentionally locked in the Toy Barrel in Toy Store of Doom. The counter with the cash register is located near the entrance. Restrooms are located at the back of the building. It has many robotic toys and puppet toys.
The Toy Barrel is a huge barrel with a plaque on it that reads the store's name in yellow letters. At the beginning of the episode, nearly twenty children are at the front door waiting for it to open. Its entrance was designed to not let anything in, or, in this case, anyone out without unlocking it first.
The only known employees are Steve and Frank the guard.
