He runs an amusement park called Hatchettland, which is essentially a shrine to himself. The Grimms and Robin Hood visit Hatchettland to ask him about the details of the day that he supposedly defeated the Wolf so that they could use the information in Mr. Canis' trial. He initially refused, and instead kicked them out of the park. By transforming Puck into the Wolf using a fairy godmother wand, they find out that, in reality, Hatchett was not the hero he claimed to be; he confesses that Mr. Canis, who was previously known as Tobias Clay (the real heroic woodsman), was watching as a old witch placed a little red-cloaked girl in a cage and placed a wolf in another cage. Clay misinterpreted the scene and attempted to save the girl, unaware that the old woman was the girl's grandmother and was trying to cure the girl of her insanity. He accidentally knocked down a jar containing the 'madness' (feral state) of the wolf and became the monster known as the Big Bad Wolf.
Hatchett was actually Clay's lazy apprentice who was o the verge of being fired. He had witnessed the whole thing, but, instead of helping, ran away and later claimed to be a hero. After Hatchett realizes he had been tricked, he refuses to testify. Luckily for the Grimms and Robin, they recorded the whole thing. It is unknow what happened to him after this, but it can be assumed that he has now lost his fame and had his role in the story of Little Red Riding Hood re-written.
When Hatchett was previously in court during the trial, he mostly used his time on the stand to advertise Hatchettland. Robin first suspected him of lying after noticing Hatchett's weak and frail body, claiming that a body like his could never even lift his grocery bags, let alone lifting the Big Bad Wolf’s body that was allegedly filled with giant rocks, and throw it into the river.
