Crocodile Mile was a great outdoor waterslide which you used during the summer. It had a small kind of paddling pool at the end that was inflated with water where you'd slide into it. I never used to make it that far though as you did have to weigh a bit if you were to make it the whole way down.
Before you got to the pool, there was a 'gateway' of a crocodile's mouth which you had to slide through. To make the slide wet, you would attach this plastic crocodile head to the hose pipe and the water sprayed everywhere.
Whatever you do, don't try Crocodile Mile when the slide is dry. I did, and broke my index finger!
