and Pterano sees Ducky holding on to a cliff and falls, but Pterano saves her from certain death. Petrie's mother arrives with a Quetzalcoatlus (who is a huge flyer) to evacuate the children, leaving Rinkus and Sierra to be caught in the meteorite's explosion, and they land back at the site where they camped earlier (quite burned, singed, and bruised). Pterano is thanked for saving Ducky's life. Back in the Great Valley, the grown-ups have a meeting and decide about Pterano's fate. For rescuing the children (spoken by Littlefoot's grandfather), Pterano's exile from the Valley will be reduced to until five cold times have passed (five winters/years). Petrie cuts in and tries to plead against the punishment, begging the grown-ups to let Pterano live in the Valley forever. However, Petrie's mother tells Petrie that even though Pterano may be sorry, it does not change what he did (erase his actions) and he must still be held responsible. Pterano, agreeing with the banishment, tells Petrie that everyone (including himself) has to take responsibility for their actions and assures Petrie that he should be fine. Accepting the result, Petrie tearfully bids Pterano farewell with the latter saying he will miss Petrie before Cera's father forces Pterano away (begging him to move on). This prompts him to remark to the latter that there are things he will not miss at all. That night, Littlefoot finds the Rainbow Faces and asks them if the meteorite really was a Stone of Cold Fire. They admit that while it wasn't, his effort to search for it was what really mattered, and reiterate that there are many unknowns to be discovered "beyond the Mysterious Beyond". Littlefoot is then momentarily distracted, and when he turns around, he finds the Rainbow Faces have disappeared in a pillar of light, and an object similar to the meteorite soars overhead and off into the night, indicating the Rainbow Faces are aliens. As his friends find him, an inspired Littlefoot reflects that there are many unknowns and that such unknowns make life wonderful.
