I thought of having an OC capture Tickles, and, out of hunger, eat him. Also, I thought of Ichy becoming a Friendly Sharptooth again (I surmise he might have been one at one time as he can talk, and that's rare as "The Old One" had never heard of one before and she's probably older than Littlefoot's grandparents and so has been around a while, and, as her herd migrates, that means she's probably been a lot of places too. Indeed, in my fanfic about the origin of Dil and Ichy, I had to make them come to the Land of Mists AFTER the Old One and her herd left, as otherwise it's possible they might have said something to someone, and the Old One would know that Taking Sharpteeth DO exist BEFORE she met Chomper.)) as he now needs to eat mammals again for food and Tickles just happens to be nearby.
Or should I leave Tickles alone?
Tickles the Megazostrodon.
