A children's game where they push a bunch of similar objects down a flight of stairs and try to get as many objects down as many stairs as possible. It requires a colonial house to play, unless the house has a basement, and the child can use the stairs leading to the basement.
A good example would be a jigsaw puzzle. It works best with larger puzzles, at least 500 pieces. The child opens the puzzle at the top of the stairs, dumps all the pieces on the top step, then uses the box to push the pieces down the stairs. The child says "Shrick!". It can also be played with other objects, such as plastic magnetic letters/numbers, Matchbox cars, small plastic toy soldiers, etc.
