Papa Sharptooth
From Land Before Time Wiki
Papa Sharptooth is Chomper's father. Papa Sharptooth is dark green in color and is almost identical in appearance to the Sharptooth from the first film, aside from having two functional eyes.
Not much is known about Papa Sharptooth, though he has been shown to be very protective of his son, breaking into the Great Valley to search for him after his egg was stolen by Littlefoot and his friends due to mistaken identity, due to mistaking Chomper's egg for Ducky's mom's egg, where he chases the children and almost eats Spike before fighting with Cera's father. He also fought alongside his partner to protect their son from an intrusive foreign Sharptooth.
Some humor is gleaned from Papa Sharptooth's concern over his son's bizzare behavior. On seeing Chomper gathering plants for Littlefoot and the others, he assumes that Chomper is collecting plants for himself and says, by subtitles, "sometimes I worry about that boy."
He has another humorous moment when he meets Littlefoot, who after hiding in the stinky flowers, smells like them. He sniffs them and says to his mate, "Anything that smells like that couldn't taste very good, anyway!"
While the four moved back a bit, Spike didn't seem to mind at all.
