This monster is supposed to the swamp monster that swallows R2-D2. However it looks nothing like the actuall prop that is supposed to represent the affordmentioned monster. The image is from visual dictionary for the original trilogy which worked in the special edition changes, however as far as I know no changes was made to the original swamp creature scene.
