This Minecraft mod adds an exciting challenge to servers where the entire world is transformed into a specific target mob.
Features
Dynamic Challenge: Each time a challenge starts, a random mob and a random number (1-100) are selected.
Worldwide Transformation: Every mob that spawns in the world is automatically transformed into the current target mob.
Boss Bar: A bar at the top of the screen displays the current target mob and progress (e.g.,
SALMON - 14/23).PBP (Piglin Protection): Piglins (all variants) and Hoglins are excluded from the transformation to maintain playability in the Nether.
Real-time Tracking: Progress is instantly displayed in the Boss Bar and in the chat upon completion.
Server-Side: The mod only needs to be installed on the server. Players do not need to install the mod themselves.
