Power Rangers Dino Thunder

Beneath the Surface (1x9)

Air date: Apr 03, 2004

Elsa hatches a plan to set up the rangers. She, disguised as Principal Randall, comes along on a field trip with Dr. Oliver's class and pretends to be helpless when the Tyrano-drones come along and create havoc at the dig site. An egg is discovered there and quickly taken to Dr. Oliver's house. As they try to find out more about the egg, Dr. Oliver goes to the site and is intercepted by a very jealous Zeltrax. Meanwhile, to the rangers' horror, a dino zord attacks them as they're trying to battle a monster.
