Flip and flop heads, bodies, and tails to make 1,000 wacky sea monsters! Best-selling illustrator Sara Ball is back with more mix-and-match fun--this time with sea creatures! In Flip-a-Fin , you get to combine the heads, bodies, and tails of ten different inhabitants of the deep--including a colorful clownfish, a glow-in-the-dark anglerfish, and a sword-nosed marlin--to create your own impossible beasts. Each flap features a fun fact about the pictured species, and inside the front cover is a chart showing the relative sizes of the featured ocean dwellers, from the seahorse to the blue whale.
