This is the VIOLET Booster expansion to the non-collectible, hysterical Killer Bunnies game. This expansion includes 55 new cards and a clear 20 sided die.
From the back of the box:
"Killer Bunnies are back again, sporting new Specialty bunnies, which make taking double turns a snap!"
"Can you escape the Bittersweet Chocolate Covered Anti-Matter Raisins or avoid a run-in at the Local Crow Bar? Pick the fabulous triple Specialty Bunny and play two cards in a row! The Laughs continue as this hysterical Violet Booster Deck delivers a deeper strategic edge and new ways to claim the Magic Carrot and win!"
