33GG DO NOT DISTURB THE CHILDREN. The vaulted ceiling of the chamber is painted as a blue sky with clouds and a bright sun, though there are many cracks in the plaster which drip brown water. Despite there being no apparent source for it, harsh white light permeates the room. More than a dozen adorable children frolic in the place, though their singsong voices sound like they are coming from far away. A large sign on one wall reads "DO NOT DISTURB THE CHILDREN".
Adventurers who stare at a child too long will suddenly experience a flash of terrible insight as the illusion on the child fades a way for a split second before returning. They will see a child-sized doughy pale humanoid form with only a gaping circular leech-like mouth with razor sharp teeth in the otherwise featureless face. Creatures able to see through illusions will be able to see the real forms of the children as well. Should they be touched, they will take on their true forms and all converge to attack the offender(s), ignoring other people unless they also touch or attack a child.

As long as no children are touched, the adventurers may pass through the room in peace. Children will not respond if talked to, but if an adventurer jumps in front of them on purpose and causes a collision it is the same as touching them.
