La Pyramide des Tempêtes (Pyramid of Tempests).
The continuing adventures of Conrad's young protagonist, Donito. This time he's on the Mexican mainland, exploring the Aztec ruins.
Donito is a young boy who lives during the times of the pirates, and can breathe under water. Full of cartoon action in a lush Caribbean setting. Conrad's watercolor depictions of the sea and underwater scenes are great.
