Peepiceek

Peepiceek was the second-in-command of Reepicheep.

When Reepicheep asked Aslan to restore his tail, Peepiceek said that if Aslan refused, the rest of the Talking Mice would cut off their tails as well. Aslan was pleased by this display of loyalty, and Reepicheep's tail was restored.

It is presumed that Peepiceek took over leadership of the Talking Mice after Reepicheep sailed off into Aslan's country.
