Garden gnomes come in four sizes: large, normal, medium and tiny. They are useful only as Rock-It Launcherammunition or as a decoration.
Normal-sized gnomes are by far the most common and stand about 1.75 feet tall. Medium versions of both intact and damaged gnomes exist, and only stand about 6 inches high. Gnomes can sometimes be found interacting with teddy bears, aligned in certain positions, playing certain roles.
In the People's Bank of Point Lookout, there is a gnome located in the bottom left deposit box. It is a miniature intact garden gnome holding a mini plunger in its left hand and standing next to a mini toilet.
Tucked away behind some filing cabinets in the northwestern corner at the same level as the door to the Olney Powerworks entrance, there is a setup of a teddy bear "playing cards" with an intact garden gnome that is using metro tickets as cards.
In a stall in the lower launch platform base, a damaged garden gnome was apparently cutting up meat with a deathclaw hand.
Also in the lower launch platform base there is a counter with a small gap down the center of it lengthwise and a red motor hanging above it. A garden gnome can be found in this gap, apparently bowling using a pool ball and 10 miniature milk bottles.
