How New Monsters Arrive Each Day
Each day, a new monster is added to The Hollow, and the hub opens a new maze for players to search. The map also grows more unsettling over time, which means the mazes players search later feel stranger than the early ones.
How the Monsters Chase Players
The monsters chase players who are investigating and searching the map for evidence, so the chase and the search happen at the same time. The event asks you to survive another night while uncovering clues, which makes the monster part of every search rather than a separate threat. Keep an eye on where it is while you look, since the two are tied together.
Why Mimic and Hiachi Are Easy to Mix Up
Monster names don't always line up with their games, and Mimic and Hiachi are the clearest case. The monster called Mimic comes from Animal Hospital, while the monster from The Mimic is Hiachi. Those names sound so close that the mix-up is easy to make, and searching by a game's name can send you to the wrong monster. Piggy is the only monster whose name exactly matches its game, so for the rest, checking the source game is safer than trusting the name.
