Trio Vehicle

The blue square, red triangle and yellow semicircle form a wonderful trio.

They can be rolled along like a train or placed on top of each other.

Place the triangle on the semicircle to make a boat with a red sail.
Place the triangle on the square to make a house with a roof.
Place the semicircle on the square to make Napoleon in a hat.

Simple yet multifunctional shapes open up great play possibilities.
