Rarely has a solid wood caterpillar been so colourful. The interlocking links lend it an unmistakable gait. The key feature is the differently designed, coordinated wheels, which accompany the moving caterpillar with a bright play of colours. But that's not all: The individual links can be stacked to form a pyramid and the caterpillar can still be pulled along without difficulty. Not one wheel loses its function - a great effect.
