"Dumbass" is a humanoid stray with no distinguishable features compared to regular human beings.
The stray appears to be a roughly 1.8m tall, humanoid being. All wanderer reports are consistent in describing its appearance. White male in his 20s with black overwhelmingly regular hair. Body proportions are pinpoint accurate to a normal human.
"Dumbass" seemingly shows up with different clothes each time. The reason for this phenomenon is not confirmed. This stray particularly appears in Level 0 for unknown reasons. Speculation suggests it may not be intelligent enough to travel to other levels. The population of this stray is not confirmed. It may or may not be the only one of its kind, but every "Dumbass" appearance is reported to have the same appearance and manner of speaking.
"Dumbass" loves to chat with wanderers. Wanderers report feeling less intelligent as they keep talking to this stray. While this stray is intelligent enough to carry out a conversation, it is not aware of our reality, and struggles to understand wanderers. It is confirmed to be a temporary state of being less intelligent. The effects can be reversed by drinking Bottled Strawberry Flavored Water.
"Dumbass" doesn't perform any kind of special interaction with the environment. It seemingly lives like a regular human being.
"I saw it as it approached our group. We first thought it was a regular human. Once it started talking to us, we immediately figured out that it wasn't a regular human. It was obviously enjoying the conversation, but struggled to understand us. It had no knowledge about our reality. We named it "Dumbass" for obvious reasons."
Every survivor encounters "Dumbass" at some point before leaving the level. Every documented survivor has encountered this stray at least once. Every question about its own reality remains unanswered. "Dumbass" doesn't seem to be aware of its own reality.
Whether multiple instances of "Dumbass" exist simultaneously in Level 0, or whether all sightings refer to a single stray, is unknown. Accounts do not agree on whether wanderers have seen multiple strays at once.
