Grebnedu

The Grebnedu was a hybrid created by Dr. Burton during the Halloween Horror Nights Jurassic Park attraction.

Appearance
The Grebnedu resembles a large snake with a large head with massive fins and a long split-jaw with a sharp beak above. Bellow the Grebnedus  small black eyes are two fish-like chunks of flesh hanging down its face. The snake-like body of the Grebnedu is smooth with spines down its back. The long lower jaw folds up into the Grebnedus throat.

Behind the scenes
The model for the park attraction was created by Jim Udenberg. (Fun fact Udenberg backwards is Grebnedu) for Universals Halloween Horror Nights. The practical effect would jump out of foliage to scare frightened park goers.
