Eclipso's search for a surviving non-avian dinosaur is beset by complications galore. Hoaxes, including an oversized Diplodocus balloon, are only a part of it. Family and friends are pressuring Eclipso's crew to quit. Bizarre nightmares about Houdini Chicken haunt paleontologist Augie Matias. Sherman Peabody's Artificial Intelligence Entity takes things a bit too literally. And purported time travelers hint at an approaching threat of cosmic proportions.

Undaunted, though, the happy quest carries on in Brazil, where a popular tourist ride might have to deal with a camouflaging Carnotaurus.

All aboard! Toot! Toot! Roar! Roar!
