Farming
You could get Bunny Statue and some wiring to spawn some corrupted bunny's only in Blood Moon where you could spawn unlimited corrupted bunny because they don't count as normal bunny's so they don't have a limit. You would need Vilethorn or a weapon that can go through walls to be effective.
