There are three rabbits in the Baby Einstein series. There is a couple, Sunny and Bach The Bunny. Bach's first appearance was in the cover of Baby Bach in 1999, but unfortunately nowhere else. He then made an appearance in Meet The Orchestra in 2006. Sunny made her first appearance in Baby Van Gogh in 2000, where she lets her discount brother Bach The Bunny pop out of a hat. She was seen again playing in her leafy field with a white picket fence and jumping in leaves. She also made an appearance in Baby Da Vinci in 2004.
