You misunderstood me. I’m saying, maybe years earlier, they were where Chomper is now. They were friends with Leaf Eaters. Something went wrong. Perhaps one or both of them was raised by Leaf Eaters. I know nothing screams friendly NOW, but what about years ago? I mean, they can talk.
Also, suppose that 10 or so years down the line (hope he doesn’t) that Chomper goes rogue. Now he’s not friendly to Leaf Eaters anymore but he’s been shunning other Sharpteeth, including his own species. Perhaps he’ll end up alone or in dire straits like those two.
If that’s true then it was MANY years ago. Dill is likely pretty old as she’s losing her eyesight and Ichy doesn’t look young either.
