Place it at the exact beat Walter enters, then follow it with the Roblox Oof sound for the group's reaction, and save Enemy Spotted for the next floor reveal so each moment keeps its own payoff.

This is a very short Walter clip from Regretevator, lasting just over a third of a second and built around one sudden character beat. It feels funny and surprising, the kind of blink-and-you-miss-it interruption that makes a group laugh before anyone has time to react. Taken from the Roblox elevator game Regretevator, it works best as a quick burst of recognition for players who know Walter.
