Poskra was a male water rat who had been expelled from several tribes. As he had only one tooth, he consumed different soups for sustenance. Poskra also enjoyed drinking damson wine, which led to his capturing of Durby and Feegle with plans to exchange them for damson wine flasks. He was killed by Vallug Bowbeast when the latter and Eefera planned to use Durby and Feegle for ransom of the Taggerung.
