The Bear Retrieval Units are a kind of KlayBird that, as their name states, retrieve bears. They were only seen in the battle of Big Robot Bil and the Clockwork Beast.
They emerge from the Clockwork Beast's back and steal Big Robot Bil's teddy bear. They smoke and drive a car similar to a Jeep. They are never seen again after this scene.
The Bear Retrieval Units resemble anthropomorphic KlayBirds that wear red spiked hats and red boots. One is tall and skinny and the other is short and fat.
