Really easy video/animation

Need a smiple video/animation based on a scene from jurassic park. The part where the t-rex apears from the bushes, the t-rex should be replaced with a turtle. This does not need to look profetional at all. Also the same when the t-rex chases the car, it shoudl be a gigant turtle. This is for a fun/school project, and does not have to be made really profressional (low cost). Heres the scene: [login to view URL]
