When three titanosaurus kids hatch from their eggs, their mom is nowhere to be found. With nothing else to do, they’re off on an adventure to find her, asking every creature they meet along the way: Have you seen our mom? After a harrowing encounter with a tyrannosaurus deep in the forest, they look under the sea and in the sky. Thankfully a pteranodon has spotted the big, huge mama titanosaurus, and the family is united.
