Nibbles and the crazy science experiment

"Buzzy Baxter really did it this time. His latest antics in science class have gone haywire. And now Nibbles, the fourth-grade hamster, can talk! Fearing Nibbles will be taken away by researchers, Buzzy tries to hide the hamster's new talent. He gets help from his old friend, Jeff Woodhouse, and a new one, Cari Perez. But the wise-cracking, trouble-making, country-music-singing hamster has different plans... Join Buzzy, Nibbles and their crew as they try to dodge trouble--but end up in a whole heap of it!" --Publisher's site.
