I'm probably one of the few who want her to stay in the great valley and be a part of the gang, but I think that could work, or they could do a final episode, with everyone, for some reason (the wirld is ending, extintion, something like that) goes to live to the great valley, maybe not Chomper but it would be nice for the ending to include him and all the other closest friends to join together, much like in the original movie... It's just a thought, what do you think?
