Blue's Mimic Creepers
This resource pack introduces a completely new gameplay mechanic with creepers in Minecraft. The creeper models and animations have been completely overhauled to look more realistic and dynamic.
Main Feature
One of the most interesting innovations is the ability of some creepers to mimic other mobs. They can take the appearance of zombies, skeletons, or other creatures, remaining unnoticed until the very last moment.
As they approach the player, the disguised creeper gradually returns to its true form, creating an element of surprise and adding strategic elements to the game.
