Carnivora Dead Claptrap
This dead Claptrap can be found in a small hidden room in the region of Carnivora, located in the Stacked Deck bandit town near the start of the region.
As soon as you enter the stacked deck, move south through the town while hanging along the left side, and you'll find an open doorway with a red light shining out. This leads to a trap door where you'll find the remains of the claptrap down inside.
