 * Bear Necessities

Fallout 3

 * Larger teddy bears can be found in various locations throughout the wasteland. Giant teddy bears can be found in the Red Racer Factory and at SatCom Array NN-03d. The teddy bear at the Red Racer Factory can be found on a hanging tricycle; the player character must shoot the bear down, or jump up to it using the nearby barrels. The giant teddy bear at the SatCom Array NN-03d must be blasted out from behind the wooden boards with a large explosion.There is also an over-sized teddy bear at Olney Powerworks in the "easter egg" bathroom.
 * Collecting different sized teddy bears: You must not have ANY other teddy bears in your inventory before or during the time you have the larger size bear, or when you drop it, it will revert to the default size.
 * Yew's bear charm has the same model as a teddy bear.
 * There are some interesting compositions involving garden gnomes and bears in some locations added by the Broken Steel add-on, specifically in Old Olney Underground.
 * Teddy bears can also be looted from feral ghoul corpses sometimes.
 * If one of the larger bears is picked up and dropped more than once it will revert to its original size.
 * The teddy bears can be sold to Midea after completing Free Labor. Wernher claims that she buys them for the baby (she also buys any other toys you have). You receive caps for every toy you give her.

Fallout: New Vegas

 * Teddy bears are unlimited in New Vegas, as they can be found in toy boxes, which are, in some cases capable of re-spawning items inside of them. Due to the very small list of items considered "toys" by these containers, the chances for bears are fairly good.
 * Other variants for the teddy bears are Sergeant Teddy and Mister Cuddles.
