Holiday Cave

Holiday Cave, very commonly known as HC, is a type of limited event dungeon that opens to commemorate an occasion — mainly holidays, given its name.

Modern Holiday Caves last two weeks, reset your level and prevent items from being taken in. Many of them have an associated currency which can be used to buy items until the next Holiday Cave. New Pokémon are often first obtainable in Holiday Caves.

Holiday Caves were "discontinued" in 2014. Staff announced that there would be a final HC and no more afterwards, as they wanted to refocus their time into making more permanent dungeons, and the time spent to make an HC event was deemed too long for the short amount of time that they would exist. Holiday Caves would still be continue to be made in the future despite this.
