Pumpkin Hill was but a small part of this odd-shaped mountain range. Many parts of these mountains, pumpkin-shaped or otherwise, are considered haunted, from the peaks of the glowing jack-o-lanterns to the deep, half-sunken mines. These mountains lie to the west of Rail Canyon.

What the... who designed this? Large spires topped with cannons a safe transportation system do not make! Home to many adrenaline junkies' dreams, and home to many Extreme Gear races. The canyons eventually run into the Pumpkin Hills to the west and the Dusty Desert of Soleanna to the east.

The Pumpkin Mountains are actually part of a larger chain that leads directly to the northern pole, where, unlike the rest of the mountains, many Mobians exist. The people here may be cut off from the rest of the world but are very open and welcoming.
