Eddie Murphy talks to the animals once again in this lovable family comedy. This time, it's up to the good doctor to defend the habitat of a lone female bear, Ava (voiced by Lisa Kudrow), and introduce her to a suitable (if intellectually challenged) mate (voiced by Steve Zahn). Raven-Symone and Kristen Wilson co-star in this sequel that features the voices of Isaac Hayes, Frankie Muniz, David Cross, Mandy Moore, Jamie Kennedy and Andy Dick.
