Quoted from delt31:I mentioned that the spinner sounds just like the penguin spinner (which I actually liked) however I noticed as they were playing that same spinner shot changes sounds from the penguin to true dino...FYI
If you listen very closely, it is the sounds of the Dilophosaurus that killed Nedry. It is the sound when he tries to have the dinosaur fetch a stick. Then it keeps following him and eventually he meets his demise.
