Iceberg Adrift (PMU 7)

Iceberg Adrift is an ice-themed PMU 6 dungeon reintroduced in PMU 7 on December 16th of 2018. To access this dungeon, you must first clear Iceberg Cavern. If you have a Key of the Winds you'll have access to the 4th boss, Suicune. A Key of the Winds is in the end room of Iceberg Frigid Waters.

Attributes
The weather in this dungeon can be Snow, Hail, Cloudy, or Foggy. On the higher floors, Hail may be more common due to Alolan Ninetales spawning, as it has the ability Snow Warning. Excluding boss rooms, there is no darkness at all in this dungeon. The traps in this dungeon consist of...

Thin Ice Room
After the first boss is a puzzle with an invisible path. If you take a wrong step you fall into the Frozen Underpass. There, is the staircase to take you back into the main room.

Puzzle 2
This room after the second boss is a simple puzzle using ice mechanics to get to the small room containing the stairs to the next floor.

Floors 29-42
On Floor 39, there is a special tile that is pink. It serves as a sign to let you know that Ditto starts appearing from this point onward. While this tile always appears, Ditto can only show up during Dawn.

Puzzle 3
After the final floor, before the third boss, is another puzzle room. You need to activate 3 switches that remove the icicles blocking the entrance to the boss room. All of the warps take you to back to the spawning point of the room.

Glalie and Cryogonal
Boss Drop:
 * Mushroom

Weavile and Walrein
Neither of the two drop anything upon defeat.

Agony
After the third puzzle room, you run into Team Agony again. Dunsparce notices you here and insists that if you came you would be killed. He asks if you are afraid of death. If you say "No", he tells you that you may still have time to leave and asks you if you will. Note that if you say "Yes" you will eventually have to say "No". Saying "No" results in him asking twice again until he tells the rest of Agony that you were here.

Boss Drop:
 * Fluffy Tail (Dedenne)
 * Burn Heal (Abra)
 * Plain Seed (Marshtomp)
 * Big Mushroom (Dedenne, Abra)
 * Mushroom (Dedenne, Dunsparce, Breloom)

Suicune
When you use your Key of the Winds on a locked door instead of going into the warp in the end room, you get access to the area beyond the door where Suicune resides. Suicune claims Pokémon lived here told it you got rid of the evil Pokémon who pursued this dungeon. Though, it tells you that you cannot have the treasure as it doesn't want it to be given to the wrong person. It asks if you still want it. Selecting "Yes" or "No" results in it saying that your answer doesn't matter and it will be the one to decide if you are worthy.

Boss Drop:
 * TM Blizzard

End Room
You have the option to use a Key of the Winds on one of the sealed doors or enter the warp in the middle which takes you into an empty room. The warp in that room is the exit to the dungeon that brings you to Snowbasin Town.

End Box
This serves as the "true" ending, and has a single Deluxe Box. It can only be reached after defeating Suicune.
 * Ice Stone
 * Icicle Key
 * Snowflake Key
 * Relic Crown
 * Heart Scale
