The Sundae Slide is an obstacle in Double Dare.

Obstacle courses including this obstacle will always have this as the first obstacle because of it having a stairway that the contestants have to get up on before the course starts. This obstacle consists of a stairway with two rails that look like a mint chocolate ice cream cone, and after the stairway the actual slide covered in whipped cream/chocolate syrup. Once the obstacle course starts, contestants have to slide down it into an ice cream "pie" with a kiddie pool as the crust, and a sentence (different every episode) written on it in chocolate syrup.

On the Halloween-themed set, this obstacle is known as "iScream Sundae".
