Dino Dex S03E07 - Dino Discovery: Part One

In part one of the Dino Dex season finale, Dex and Kayla need help taking on the Colossal Squid, Megalodon, and Albertonectes in their time-bending submarine. It's clear who they should bring in but, when Dex doesn't want to call Dana, it's up to big sister Saara to find out why.
