However, he misses Ducky and flies into a wall. The gang find him and ask him if he is ok. He, believing Leaf Eaters to be dumb and cruel animals, is shocked that they can talk. Cera sarcastically replies that they've been able to do that for years. Now fearing that he'll die like his father, Ptero pleads for them to spare him, saying he's just a kid.
. Littlefoot and the others, however, continue to be nice to him. They see that he is tired and offer his rest and food. He is glad to get Tree Stars, which he could only get when he snuck them when he was with his mother. He is amazed that leaf eaters seem so nice.

Meanwhile, Agatha and her Sharptooth flyers look for Ptero. They aren't able to find a trace of him in the . The other flyers seem to show some concern for Ptero, though Agatha's concern seems to be more that she wants to hold him under her thumb than true motherly love.
At one point, Agatha comes to the Great Valley. She tries to grab a young Swimmer but is thwarted by Ptero. Agatha is affronted by her son’s change in loyalties. However, she seems truly concerned, asking if the evil leaf eaters harmed him. He tells her that Littlefoot and the others are nice. She laughs and says, "Your father once trusted them too. They killed him for what he was. They'll leave you when they find out the truth. You just watch." She sings "Listen to Mother" again. He agrees to reveal his true nature to the others and she leaves, planning to keep a close eye on him and come back with her Sharptooth flyer friends.
Littlefoot and the others come back, asking Ptero where he has been. Ptero, unable to keep it from his new friends anymore, confesses that he is, as he believes, a Sharptooth flyer. The kids are taken aback and Ptero, feeling that they won't like him anymore, turns to go.
However, Ducky grabs him and pulls him back. She says "Oh, we wouldn't dislike you for being a Sharptooth. Oh no, no, no. That wouldn't be right. No it wouldn't." Ptero says that he's eaten creatures like them. However, much to his shock, instead of turning him away, they offer him bugs to eat, which he likes. They tell him that they have a and so aren't repulsed by him.
Ptero, thrilled, sings "Friends Like These" in appreciation of his new friends. However, soon after the song is done, Ptero moves too near Petrie, and, opening his mouth to talk, Cera, who has a sort of paranoia like she did with in the fifth movie, cries "Petrie, look out!""
Ptero, feeling that there might be more like Cera and feeling betrayed, flies off, crying. Littlefoot and the others tell Cera off. Cera feels bad for how she treated Ptero.

This time, Ptero stands up to her and says he's not leaving, that they've been treating him better than her and that, whatever the bad leaf eaters may have done to his father, Littlefoot and his friends are not like them.
Petrie is confused and asks Ptero why a Sharptooth would eat Tree Stars, as even Chomper couldn't do it. Ptero knows that Agatha only eats meat and so is confused. He stares at Petrie and soon comes to realize that Petrie and he have some similarities in appearance, and also both eat tree stars. He concludes that he is part leaf eater. He and his new friends cheer at this revelation. However, Ptero, furious at Agatha's deception says he won't be going back with her as he was treated better here than she ever treated him.

She doesn't specially say that she ate him, but says "Well, dear, I, er, unrestrained my nature. He never stood a chance." , grinning. Ptero, now knowing the truth about his mother, says he'll never go back with her now and that's she a murderer and can go back to the Mysterious Beyond alone.

In the meantime, Littlefoot and his friends , not knowing that the grownups are coming, beg Ptero not to go with her. Ptero says that if he doesn't, they will die. They say that they'd rather die than let him live the rest of his live miserable having to be a Sharptooth and please Agatha.
