Meet Ivy. She is 19 years old and is a headless hedgehog. Ask where is her head? The fact is that she was originally born without a head. At first, the doctors thought that she could not be saved, but then they found a sign of life in her, which surprised them. They studied her and said: She may not rely on food or drink, but the only thing is that she cannot see, hear or speak without her head, so she will have to navigate and recognize speech on vibrations, and express emotions through body gestures. She fully learned all the vibrations at the age of 12. And there is one more plus: If an ordinary creature has a field of vision in one direction, then Ivy, given the vibrations, has a field of view as much as 360 degrees, so she can easily dodge an enemy, regardless of where he is, and strike. Her weight is gained from her height, so she will have to maintain her figure. And so she is kind, energetic and a little mischievous, so it will be a rarity for all Mobians to have such a headless friend.
