Fire Mountain (battle course)

Fire Mountain is the challenge level of Dino Domain in Diddy Kong Racing and its remake Diddy Kong Racing DS. It can be unlocked after obtaining the Wish Key in Ancient Lake. In the Nintendo DS remake, Fire Mountain can be unlocked from Taj's Wishes Menu by paying 30 Coins for the "Battle Stage 1" option. Each racer uses a Plane in this stage, and their objective is to be the first to hatch three eggs. The official Diddy Kong Racing website suggested using Pipsy for this level. In the canceled 2001 Diddy Kong Pilot, there is an unfinished battle course in a leaked build, Hatch Match, which appeared to have a similar objective to that of Fire Mountain's, as racers could also pick up eggs. This type of battle mode is not featured in Banjo-Pilot.

Description
Fire Mountain is set in an enclosed, circular location which is enclosed by a large rock formation. Fire Mountain has volcanic scenery in the background matching that of Hot Top Volcano. With 4 differently colored nests in the corners, a small pit of yellow lava appears in the center and contains a few eggs, which are pink with light blue spots. Racers can fly here to obtain an egg and then carry it back into their nest. Each player's nest appears on a ledge in the higher portion of the stage, with a large mugshot and a different color showing which player it belongs to (red, yellow, green and blue). Shortly after a player takes an egg from pool, another egg spawns in its place. In the lower part of the stage, there are red Weapon Balloons on a rock platform, around the perimeter area, and a large green dinosaur walking around the stage. The pilots' starting areas' tops are recolored with green grass in the DS remake.

The HUD is displayed from the top screen, and it displays an icon of each player and the number of eggs they have hatched. When a racer puts an egg into their nest, they must wait a couple of seconds for it to hatch. When the egg of a player is busy hatching, an icon of it slowly flashes on the HUD beneath their mugshot. When an egg hatches, its shell cracks slightly, with two eyes peeking out from it, and the egg stops flashing from the HUD.

Players have a few ways to steal an egg from their opponent. They can do so by firing a rocket at their opponent, causing the target to drop the egg they are carrying. Also, while an egg is currently hatching at an opponent's nest, the player can take that egg from them. They cannot steal hatched eggs.
