Professor Screweyes' Eccentric Circus

"Ladies and gentlemen, welcome to the most terrifying show on the planet Earth, Professor Screweyes' Eccentric Circus! We will scare you! We will frighten you! We will shock you witless with our dreadful, terrifying, vile, monstrous programs!"

- Professor Screweyes, owner and ringmaster of the Eccentric Circus.

The Eccentric Circus, better known as Professor Screweyes' Eccentric Circus, is a modern-day travelling carnival owned and run by the sinister time-travelling genius Professor Screweyes, the main antagonist of ''We're Back! A Dinosaur's Story''. This circus-themed business along with its scary features and its huge namesake circus tent is a perfect example of the Circus of Fear trope.

Unlike many other circuses, it is geared towards fear and terror,and features things like ghosts, zombies, demons, monsters among others that frighten and scare visitors.

The circus was ultimately disbanded by Screweyes' good twin brother Captain Neweyes with the help of giant scissors from his ship which cut down the circus tent, after Professor Screweyes' plan was ultimately foiled by the dinosaurs, Louie and Cecilia.
