“A barrel of giggles, exaltation of friendship, and slight science to boot.”– Kirkus Reviews
“Ohi’s (Where Are My Books?) puckish cartoons and Reynolds’s (President Squid) fine comic timing light up this story about how friends help each other. – Publisher’s Weekly
“Like Mo Willems’ Elephant and Piggie books…Just the right amount of silliness enhances the tale of the already comical,
bow tie–wearing, google-eyed Sea Monkey and the bright yellow, puffed-out Bob.” – Booklist
“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” – School Library Journal
“Two great friends have two big worries. Bob is afraid of floating to the surface and Sea Monkey is scared of sinking to the bottom. Filled with vibrant illustrations, large colourful text uniquely describes the qualities of heavy and light. When the friends stick together they realize they are safe. Ages four to eight will love these characters, while they learn about friendship and buoyancy.” – Calgary Herald
“This is a fun story that shows that sticking together can be a good way to conquer your fears. The text is accessible to young independent readers, or this would be a great read-aloud.” – Looking For a Good Book, June 2017
