A clown's mask, but specially made to be wearable by children, and also to strike fear into the hearts of victims.
Note: After you leave the simulation the mask will be removed.
The non-simulation version of the mask in Point Lookout has a Damage Resistance of 1 and can be repaired with other copies of itself. In addition, it decreases Perception by 1 while increasing Melee Weapons by 5.
The mask is obtained along with the slasher knife during the Tranquility Lane quest if one decides to help Betty kill all the residents of Tranquility Lane. It is then located in the doghouse beside the abandoned house and is automatically equipped when upon receiving it.
At the end of the quest or upon exiting the simulation, the mask is automatically removed from one's inventory. The glitch which allows the player character to take items out of the Anchorage Reclamation simulation does not work here due to the fact that the item is a "quest item" and cannot be removed by the player character.
The Pint-Sized Slasher mask can be found in two locations in Point Lookout:
If accessed outside the simulation via console command, it cannot be unequipped without using unequipitem <base_id>, nor removed from one's inventory without resetting the quest flag by using setquestobject <base_id> 0.
