Special Containment Procedures: New XXXX-PARTY events are to be immediately reported by Foundation field agents
Description: SCP-XXXX is the designation for a humanoid entity with no physical abnormalities other than having a single Vespula squamosa1 specimen in place of a head. This specimen is 4 times the size of an average member of its species. SCP-XXXX during appearances wears a rainbow-colored dinner suit.
Once per month, on a seemingly random day, an XXXX–PARTY event will occur. SCP-XXXX will appear at a child's birthday party within the United States in which the aging child is 4 – 11 years old. All individuals attending the party will come under a memetic effect, and will not ask any questions or display surprisal despite SCP-XXXX's appearance and actions.
When SCP-XXXX first enters the area of the gathering, all attendees will gasp and exclaim "it's Birthday Wasp!" in unison. SCP-XXXX will perform various actions to entertain the individuals at the party, such as playing songs on a ukulele2 or making shapes out of balloons. SCP-XXXX can only communicate in buzzing sounds, but the attendees will perceive it to be coherent speech.
Addendum XXXX.01
XXXX-PARTY Event 9/3/2001
Partygoers are talking with each other, and eating.
SCP-XXXX abruptly kicks the front door of the house off its hinges, which flies forward at a rate of ~45 km/h before crashing into a wall.
All attendees in unison: [Gasp, and turn to face SCP-XXXX] It's Birthday Wasp!
SCP-XXXX makes a buzzing sound, and sits down on a chair in the living room. The children gather around it, sitting in cross-legged positions.
SCP-XXXX reaches from behind its back, and pulls out a hardcover book labeled "Wasp Stories to Tell to Your Kids". The children cheer in excitement.
SCP-XXXX makes a motion akin to clearing its throat.
