The creature that initially looked like a furry ball became like a deflated balloon.
"Huh? So this is its true form?"
Gradually, the furry ball flattened into what looked like a piece of thin and soft animal fur.
At the center for the fur coat, there was a mouth that belonged to a primitive creature, spiral-patterned teeth filled the whole mouth.
The creature had no eyes, no nose, no ears, no limbs, and no tail.
Its balloon-like protective layer seemed to have the function of self-sealing and sensing sound waves naturally.
The way the creature performed self-sealing was to completely hide its breath and body temperature inside its balloon-like furry body and become one with the environment.
At the same time, due to its long-term evolution in the sound wave setting of the Burrow World, it had learned to hide from being traced by the Ultrasound Positioning Sorcery easily.
The so-called "hiding" was always based on the perception of other creatures.
