Piranha Pit

Piranha Pit is a multiplayer stage in Splatoon and Splatoon 2.

Splatoon
Piranha Pit is a map located in a quarry. Piranha Pit has two defining gameplay features. The first of which is that it's a wide map with a small distance between the two spawn points compared to other maps. The second feature is that it has conveyor belts that will move in most modes.

The map itself consists of the spawn areas, the center, and the side areas. The right leads to a pathway that drops down three levels before reaching the center, further right leads to a platform that leads to a smaller section with a ramp and a path leading to the center. The front of the spawn drops down, with a conveyor belt leading directly to the center. The left has a tower that can be walked up via a slope, leading to a grated section. Further left leads to a small inkable platform that leads to the conveyor belt going to the side areas. These camps on the edges of the map contain most of the ink-able turf in Piranha Pit.

It features ten conveyor belts in total; one is in front of each team's spawn point facing away from it. Two are located in the center, and three more to the left of each spawn, near each Side Camp. Ink spread on each conveyor belt counts towards each team's score, and the ink on the conveyor belt will wrap around when it reaches the end of the belt. They each feature two conveyor belts, one going up and another going down, and can be located to the left of each team's spawn. The center of the map contains two conveyor belts, separated by a divider, two alleys, and two small areas to the side. This is where most fighting over turf may take place, as players have to go through here in order to reach the opposing team's Side Camp.

Splatoon 2
In Splatoon 2, the center conveyor belts are no longer touching and now has inkable space between them. Sponges have been added at the end of the conveyor belts that are in front of the spawn.

Splat Zones
Piranha Pit has two Splat Zones each located in the open space immediately in front of each Team's spawn point by the central conveyor belt ramps. The only way to get between the zones on ground level is through the small alleys in the center, however from spawn or with the use of the conveyor belt ramps players can take the slightly higher ground and have a little more freedom in how to infiltrate the opposite zone. The two conveyor belts in the Side Camps have also been disabled.

Tower Control
The tower is located at the center of the map between the two conveyor belt ramps where a wall would normally be. The tower will first move towards your team's side before moving through the ground level alley to the enemy's half of the stage. From there the tower will travel to the edge of the middle ground before making a U-turn and reaching its goal.

Rainmaker
The Spawn Point in Rainmaker is moved towards the left next to the tower in front of the team's normal spawn position. The Rainmaker is located at the center of the map between the two conveyor belt ramps where a wall would normally be. The Rainmaker must be taken to a goal on the far opposite side of the map on the small island in the Side Camp. Many of the conveyor belts do not function in this mode, with the exception of the conveyor belt ramps in the center, and the ones next to each goal. Lots of boxes have been added over holes to aid in attacking the enemy team.

Trivia

 * Prior to Version 2.5.0, it was possible for a player to perform a glitch in Piranha Pit in Tower Control game mode. the player was able to make their inkling body boneless with the roller type weapon by moving the roller in the conveyor belt and sticking it to the tower.
 * The machine in the distance is a bucket-wheel excavator, used for continuous digging in large-scale open-pit mining.
 * The Great Zapfish swims in the water off to the side of Piranha Pit by a raft, and can be seen coming up to the surface occasionally.
 * When forced to load in Battle Dojo, Piranha Pit lacks the conveyor belts entirely. It is unknown what causes this.
