Broodmother's Nest
Squeak Squeak!
Broodmother's Nest is the home of the Undead Rat Broodmother, appearing only during Halloween in addition to all the Plaguespace wormholes appearing. Unlike typical Plaguespaces, Broodmother's Nest is quiet, until you approach the wormhole leading deeper in, to Broodmother's Lair. Getting within 300 distance of the wormhole will cause five Royal Undead Rats to spawn, along with an Undead Rat Queen who has a bit of a longer respawn. Sometimes a Royal Undead Rat will leave the Broodmother's Nest. Near the entrance is a rotting space cheese that emits rotting particles, near the entrance deeper into the nest emits rotting particles and near the entrance are two space cheeses orbiting the entrance also emitting rotting particles, with a chunk of cheese orbiting one of the bigger pieces.
To enter Broodmother's Lair, you must collect 10 Royal Rat Glands from the rats found within Broodmother's Nest.
