Larry is a heavyweight boxer on the verge of becoming world class and is currently in preparation for his revenge match against Richie ‘The Red’ Connors. With one week to go, Larry doesn’t think that he’s made enough progress during his training camp – his feet and hands still feel too sluggish. Determined to get better, Larry gets up early one morning to train in his barn that he’s converted into a gym, but instead he is magically transported away to the Land of Eustress by stepping in a cowpat, lovingly deposited by his pet cow, Heavyweight.
Confused and distraught, Larry soon finds out that his cow is the High Priestess in the Land of Eustress, and was commissioned by the Council of Eldars to fetch a warrior to defeat the evil dragon, Murdock. Once he is charged with this task, Larry makes his way through the land, with a red squirrel as his guide and companion. On his travels, Larry learns more about the dragon from the creatures he encounters, and often finds himself having to undertake tasks in order to gain help and respect. From fighting a bear and a hornets’ nest to helping some spiders build a block of flats, Larry undertakes numerous tasks that are both physically and psychologically demanding, which ultimately help him to become a better boxer.
