Dynamo Sands (PMU 7)

Dynamo Sands, also called DS or Dynamo by players, is a dungeon reintroduced from PMU 6, located in Tanren Desert. The main types are Electric and Ground. It features several puzzles and exclusive Pokémon. To access it, one must use the move Dig on a specific quicksand pit in the Tanren Desert depending on the time of the day.

There are two rest stops in the dungeon. The middle section of this dungeon, Dynamo Sands Labyrinth, takes the player to randomized floors until they reach B99F. It can however be skipped if the player has already completed Dynamo Sands. The weather can be sunny or sandstorm.

Crossroads
After Floor 20 is a puzzle with several blocks. In the top-left of the room is stairs that are the exit. You can make some of these blocks disappear for a time by walking up to them, some cannot be passed through again once you go through. In the top center of the room is a warp which takes you back to the spawn point, as you will be trapped if the puzzle is done wrong. Cacnea will spawn here as disruptions.

Labyrinth Entrance
After Floor 40, there's a rest stop with a Kangaskhan Storage and Chimecho Assembly. There are two staircases; the ones at the top will bring you into the Dynamo Sands Labyrinth. The upper-left one will skip the Labyrinth, it will take you straight to the Corridor of Power. You have to use Rock Climb on the tile near it to reach it.

Dynamo Sands Midpoint
Once you get out of the Labyrinth, you come across another midpoint with a Storage and Assembly, and a heal bed next to the Assembly. This room has the 'Safe' moral, any parties are disbanded but can then be recreated, and any Mystery Eggs can be hatched. The stairs to continue are initially blocked off, there is one switch on either side of the map that will unblock the respective side for a short time.

Corridor of Power
After the midpoint is a room called the "Corridor of Power". It has a several Electivire that can know the moves Psychic, Earthquake, Uproar, Discharge and Hyper Beam. Some are inside of the enclosed hallway while others are outside of the boundary, making this room an intentional challenge to live through.
