Two delightfully anxious friends learn that they can overcome anything—even gravity—in this humorous and heartwarming picture book from bestselling author Aaron Reynolds and illustrator Debbie Ridpath Ohi.

Bob the puffer fish and his best buddy Sea Monkey may be little but they’ve got one ocean-sized problem. Sea Monkey’s terrified he’ll sink straight to the bottom of the ocean. After all, he’s heavy, and all heavy things sink, right? Bob on the other hand is worried that his puffed up frame will float up above the surface. He’s light, and all light things float! How will they stay together when the forces of gravity are literally trying to pull them apart? By holding hands, of course! Sea Monkey and Bob learn that sometimes the only way to overcome your fears is to just keep holding on…

A sea monkey who is afraid of sinking and a pufferfish afraid of floating to the surface conquer their fears by sticking together.

"This is a humorous story of friendship and a great way to introduce the concept of buoyancy in a classroom.... A fun addition to any library and especially as part of a science lesson"
