 While most of the characters in the story were faithful adaptations  of their manga counterparts, Woodchuck (the thief) underwent some  unexplained changes. In the anime he is a fairly nice person who is  rather clumsy in his thievery and a bit on the lazy side. In the  original manga he has far less of a heart, is much greedier and  better at thievery, and ultimately works to meet his own needs  rather than the needs of Parn and the others.
