The Junk Depot is located within the Guild Area in Fossil Fighters. This is where a lot of tools are kept. McJunker owns the place, and Holt works there as his apprentice. The player has to go there to get a key component for the vandalized mine cart that takes you to the fifth tunnel. The player must fight Holt here and needs to use a V Raptor (found in Greenhorn Plains) in the fight. At the end of Chapter 3, McJunker says the player can see them there. After the player beats the game, he/she can fight McJunker anytime.
