Sophie and Bear are two friends going for a visit to New York City. She is excited about its size and beauty whereas he is apprehensive about its size and scariness. In a taxi cab, Bear wishes the driver would slow down whereas Sophie loves moving fast. The same differences hold true for their view of subways.

In this picture book designed for children from 2 to 5 years of age, writer Frieda Wishinsky and illustrator Sean L. Moore capture and convey the high energy of New York City and the divergent responses to it. The trip enables young readers to take stock of their responses to new experiences outside the security of home. What's Up, Bear? also makes clear the meaning of "different strokes for different folks" and the value of friendship above all else.
