Ol' Mama Squirrel has raised many babies and kept them all safe from predators, but she may have met her match when a determined grizzly bear threatens to eat her entire family tree.

Dr. Grizzly gives the Berenstain cubs a regular checkup.

"Papa Bear and Grizzly Gramps are the best dads in Bear Country and the cubs want to show their love. Working together with Mama and Gran, a special fishing trip and picnic are planned for Father's Day. Will Papa and Gramps bring in a big catch of fish or will they catch something even better?--Page [4] of cover.

"This summer, Billy will fly across the country, hike a mountain, float a river, dodge a grizzly bear, shoot down a spy drone, save a neighbor's cat, save an endangered panther, and then try to save his own father. Carl Hiaasen tells a wickedly funny, slightly twisted tale about families, figuring out what's really important, and knowing when (and when not) to let things go."--Amazon.com.

The Bears are on a steam train trip across Bear country. Mama and Papa enjoy the scenery but the cubs want to learn about the train. With luck, Grizzly Jones might let them blow the train whistle.
