Octagon Snail

The Octagon Snail is a puzzle and a marble run in one: you have to arrange the blocks in the right configuration, according to colour and size, to create the spiral for the marble to follow. So there's plenty to learn, and satisfaction at the end.

Given the concepts involved, this is a toy that will come into its own for the three-and-ups, but it should also keep younger children happy too. Could it even be that one toy that will entertain older and younger siblings simultaneously?
