Being the largest dinosaur in his area, Boris is often asked by much smaller creatures to protect them, and he often accepts, whether he is given food in return or not; he often is. Sometimes, he'll find someone who he believes deserves "protection," and he offers it in a very special way...by eating them up! Often, these unwitting creatures end up squirming the whole way inside him; such lively prey is preferred for Boris as their squirms help him process his real food as a digestive aid while keeping them safe...most of the time.
