Once there was a little mouse named Alexander who dreamt of being big and strong and courageous like his favorite superhero, Mighty Bruno. Alexander and his family are all afraid of Rats, the cat with the long, sharp claws who lives upstairs, and Alexander's father, who has lost part of his tail to her, is so terrified that he no longer dares venture upstairs in search of food for the family. So Alexander must put his dreams of glory to the test. He fashions a bear suit, which makes him feel bigger and stronger and brave enough to undertake the dangerous quest for food. And he succeeds--until the last minute, when Rats sneaks up behind him and sinks her teeth into his bear suit. It looks like curtains for Alexander! How a plucky little mouse in a bear costume saves his family from starvation and wins the heart of a not-so-vicious cat in the process is a charming variation on the popular cat and mouse tale.
