An imposter Mujee Egg! The Imposter Eggs lacks a bone structure and swallows an entire egg whole. It is able to reproduce the scent and pheromones on the other eggs nearby to remain undetected and cared for by the parent of the eggs it's eating. Slowly digesting the egg, they remain in the same shape until the parent leaves the nest for food, to which they expel the empty egg away from the others and swallow a new egg. By the time the eggs are supposed to have hatched, the Imposter Egg moves on to another nest.
