GasMart is a convienience store that belongs to Mr. Brick. Larry is the only employee aside from Mr. Brick himself. It's quite small on the outside but very big on the inside for some reason. This was discovered on accident when Birdley accidentally knocked down a wall panel in the storage room.

Interestingly, Birdley and Mr. B used to be co-workers here. Then Mr. B got a job at Technopark and subsequently Birdley.
