Ruby: What happened Chomper?
Chomper: Well.. Um... I was chasing my tail and I kind of... caught it.
Ruby: Oh dear! We will need to talk to the healer! To the healer we will need to talk!
Later at the healer's cave:
Healer: Well, unfortunately, it looks like you caused significant damage and we will need to operate. If the infection gets worse then we may need to amputate.
Chomper: Oh no! My tail! I can't lose my tail!
