Garden gnome (Fallout 3)

There are two types of garden gnomes in Fallout 3, Damaged ones are much more common and intact ones are somewhat rare. They are useful only as Rock-It Launcher ammunition or as a decoration.

Damaged Garden Gnome
Because of its weight of 4 and low value of one, a Damaged Garden Gnome is barely worth picking up to trade for, unless you're extremely low on caps or can carry a lot of weight. They are most often found outside houses or what remains of houses.

Intact Garden Gnome
One intact example comes with the Pre-War Theme for your house in Megaton. 16 tiny intact garden gnomes can be found (being used as chess pieces) inside of one of the SatCom Array NN-03d towers. It is also one of the items you have to activate for the Tranquility Lane Failsafe. Some gnomes are found shrunken in size, however, dropping them after putting them into your inventory returns them to their original size.

Several Intact Garden Gnomes can be found when playing through the main quest in Broken Steel.

There is an intact Garben Gnome in front of a house near the Jury Street Metro Station. While standing at the gate of the fance around the radio tower nearby, it's the house to the NorthEast-East, a stonethrow away.

At least two Intact Garden Gnomes can be found in Tenpenny Tower.

People have also placed gnomes as decorations, and then they have later mysteriously changed positions, even onto tables, and other furniture...

You can also find intact ones in tranquility lane, but they are impossible to take out without console commands.
