Beneath the Surface.
Episode Description:
Dr. Oliver and Principal Randall take the students on a dig, using that pretense to hide their real motive of finding a Dino Egg. Pulling a bait and switch on the Rangers, Randall, who is Mesogog's henchwoman, Elsa, in disguise, manages to steal the real Dino Egg and hatches the Dimetro Zord. After a brief battle, the Rangers tame the Dimetro Zord, who helps to defeat Scorpex, the latest monster with the saw blade ability.
