Ten year old Walter Kettle is an ordinary boy until he eats a nut. Then he transforms into unlikely superhero Squirrel Boy whose only superpowers seem to be a large bushy tail, an ability to climb trees and run very fast, and a sudden understanding of ''Squirrelish'' (the language used by squirrels). In his second adventure, we join Walter to find out whether these unusual powers will be enough to defeat the determined Squirrel Hunter and save the squirrel population in the local park.
