This was a pretty boring episode. The Titans fall through the ice at the arctic circle along with Dr. Light. There they meet up with a girl named Kole, who can turn herself into crystal and a caveman called Gnarrk. The dinosaurs only appear near the beginning, and then don't show up again for the rest of the episode. Kole, I wanted to know more about her, I don't read the comics, so I needed more information, why is she down there? How did she get her powers? Until the very end, it doesn't even seem she can move while in her crystal state. For the majority she just turns into a petrified stick for Gnarrk to hit dinosaurs with. Come on.
The comedy elements didn't really work. Beast Boy wasn't funny once, the moment where Cyborg's mouth turns into an elephant snout, it was just weird, not in a good way. The Titans don't do much here either. Dr. Light was fun, but some of the light puns where just bad. The action is dull, the final battle was marginally decent, nothing more. I didn't really like this episode, there's nothing majorly wrong with it, it's just boring and uninteresting. I liked Kole, but I wanted more information about her.
