Billy has a bear called Griz. A Grizzly Bear. And the two friends have all kinds of wonderful adventures together. They go exploring, they play hide and seek, they eat peanut butter and honey sandwiches, share secrets and tell jokes. They even go out at night to do some star-gazing - and their favourite constellation is the Great Bear of course. Griz is the best friend a boy could possibly have. And is he a real Grizzly Bear or a teddy bear?
