Dover Publications has the best deal on the net for coloring books! For $3.95 plus S&H you can get 32 pages of underwater reef pleasure! Who says the blue-ringed octopus (below) has to have blue rings? Why not lemon, or dirt brown (to signify where you will be buried should you touch it)? Stocked full with corals, nudibranchs, and oh yeah, those swimming vertebrate things that Mike the traitor likes, this coloring book will be sure to inspire your little ocean diver! Just look at the pretty coral on the cover. Its too bad those blobby orange stripey things are in the way.
