 SCP-465-1 is a large two-piece cardboard box decorated with a faded confetti pattern popular in the 1970s. Other than a large printed label on the top of the lid marked Party in a Box, no indication of contents or manufacturer are found on any portion of the object. When any human subject completely removes the lid of SCP-465-1, an array of decorations, furniture, and a group of at least 20 people, collectively SCP-465-2, appear spontaneously in the room. These individuals proceed to celebrate rockously and actively attempt to include the subject in their festivities, primarily dancing in consumption of alcohol.
