Robocroc (2013)

When experimental military nanotechnology accidentally gets loose in the wild, a crocodile absorbs it and is transformed into a half-machine killer with armoured skin and an appetite to match. Corin Nemec's hero and a few allies try to stop the creature before it reaches a busy water park, while the military tries to cover the whole thing up. RoboCroc is a cheerfully over-the-top made-for-television creature feature, meant to be enjoyed for its absurd premise and effects-heavy attacks.
