The Lost Tinker Goblin of Fog Mountain is a character Finn mentions in the episode "Paper Pete." Finn suggests they take the wobbly table that Jake is reading the Rainicornicopia on to him for him to fix. Jake believes that this adventure may be made-up, so the character himself may also be make-believe. Since he never appears onscreen, all that can be inferred is that his appearance resembles a Goblin. He apparently lives in a region called "Fog Mountain."
