Marvin is a snow imp playing a prank on Explorer Jack. When he and his companions, Benny and Marius, were working on a mission in Gielinor, Marius got cornered and interrogated by Jack, who they thought was being greedy. They concocted a plan, tricking him into thinking the White Lands were full of riches, when in reality it was merely yeti dung, which would smell terrible once warmed up. They enchanted the dung. Despite their intents, Jack actually ended up pleased, considering the dung a valuable resource.
