Book excerpt: In a high-energy sequel to I Am Bear, the dance-loving star rolls out a variety of dance moves and inspires kids to try some of their own. Get up, get down, hit the ground . . . Bear’s in a dancing mood, and his friend Bunny is happy to help out with the boom box. With moves like Furry Breaking, Running Bear (you run but don’t go anywhere), and the classic back spin, who could blame observers who might want to bust a move of their own? Actor/rapper Ben Bailey Smith (aka Doc Brown) and artist Sav Akyuz team up again for a lively two-step with the multitalented Bear.
