We're Back! Another Dinosaur's Story.

A year after the events of We're Back, a Dinosaur's Story, the four dinosaur friends, Rex the Tyrannosaurus, Woog the Triceratops, Dweeb the Hadrosaur, and Elsa the Pterodactyl, have been enjoying their new lives at the Museum of Natural History! "wink!"
And their child friends, Louie and Cecilia, have gone back to their normal lives with their families. But even though Professor Screweyes died, he left behind minions to finish his work, and they have learned that Louie and Cecilia have remnants of the Brain Drain that Screweyes used to turn them into monkeys still in their bloodstreams. And they have started to transform back. Slowly.....but surely. The dinosaurs and Screweyes's brother, Captain Neweyes learn that a group of Screweye's fans want to restart the Eccentric Circus, and put Louie and Cecilia in it! Will the dinosaurs and Neweyes save their friends and crush the Eccentric Circus once and for all?
