It can't stay if it's going to be destructive and disruptive, and if it's going to find ways of sneaking back in--to continue to be destructive and disruptive--then no, I don't suppose it's too far. It'll be a change of meat for the cooks, and some different hide to work into leathers, and so on.

Although we could see if there's anyone who wishes to tame it to ride it first. Strange that it seems so docile around people. Could make a fine, unusual mount if it could stay in a stable.
