In Artemis Fowl and the Lost Colony, Mulch, now a PI (private investigator), is needed by Artemis Fowl to foil a plan to expose the missing demon race. He helps them break into the Paradizo chateau, rescue Minerva Paradizo from the clutches of Billy Kong and while Holly is away in Limbo, he runs the PI firm with another ex-criminal partner, Doodah Day. The Time Paradox While Artemis and Holly are trapped in the past, a younger Mulch rescues them from Artemis' younger self. He then agrees to accompany them to save the silky sifaka lemur for a stupendous amount of gold. The three friends are able to successfully capture the lemur by having Mulch tunnel underneath it and steal it away from Dr Kronksi, but Holly is kidnapped by the younger Artemis. Mulch stays with the lemur until Artemis rescues her, and they return to Fowl Manor. He is accosted by Opal Koboi who drains his memories from the past three days to find Artemis and Holly, and doesn't remember the experience (nor his shoe size). The Atlantis Complex Mulch Diggums, alias Tombstone, is in The Sozzled Parrot, a dwarf hangout club, where he hears of two dwarfs going on a client's request to kill or mind-wipe Mulch's friends, Domovoi and Juliet Butler. Hearing this, he decides to go along with them and sabotages the mission. The Last Guardian Mulch Diggums saves Artemis's life the first time when they are confronted by the Berserkers. Then he risks his life to return to the crashed shuttle to get the weapons etc. but he is sensed by Opal Koboi who sends carnivorous Berserker possessed rabbits after him to devour him, however, it turns out to be Mulch Diggums who does the eating. On returning to his 'man cave' he sees Gruff the troll in it and begins fighting him for possession. Later when Artemis and Holly are surrounded by Berserkers (again) it turns out that Mulch is riding Gruff as his predecessors rode trolls in the war against humans. He helps to save Artemis and Holly and jumpstart the plane. In the end, when Artemis has sacrificed himself, apparently, Mulch convinces the Council that he was the sole being who set everything right References Artemis Fowl characters Fictional dwarves Fictional criminals Fictional thieves Fictional private investigators Male characters in literature Literary characters introduced in 2001 Fictional gangsters Fictional prison escapees fr:Personnages
