“Feaster Grievings,” an original, limited-time experience running April 1 through May 2, 2026, at the year-round horror venue inside the AREA15 District in Las Vegas.

The experience is built around the story of an unfinished horror film that has resurfaced, with its sinister lead character, Feaster Bunny, determined to finish what he started. Upon entering Universal Horror Unleashed, guests receive a call sheet casting them as part of the production, pulling them into the narrative as participants rather than spectators.

The Feaster Bunny character originated in the 2011 Halloween Horror Nights haunted house H.R. Bloodengutz Presents: Holidays of Horror, part of Halloween Horror Nights 21. The character has been given an updated look for his Horror Unleashed appearance.
