Bunny Hideout
From Starsonata Wiki
Bunny Hideout! The place of residence to the Easter Bunny and Zombie Easter Bunny. Although only on special conditions. To new comers, the galaxy is empty, displaying a sign saying "Wrong place, wrong time. Maybe someone else knows the right place and the right time."
Once contracted by Elmer Fudd, when you enter the sign disappears and the Easter Bunny appears. Once you've completed the mission, you can return here again to take on the Zombie Easter Bunny
