true story of a late monster that appear when an american industrial plant begin pollute the water . amusing and though not really good and monster film have lot of people try to get the monster and find out whats go on but not in a completely involve way . give it point for give u a giant monster that they clearly build to scale for some scene but take some away in that it look like a non threatening puppy . an amusing exploitation film thats enjoyably silly in the right frame of mind . ( my one complaint be that the print use on the elvira release be so poor that it look like a well worn video tape copy that be past it prime 20 year ago . ) .
