Awwwwww, Drumheller

The Final Four take a trip to the Badlands of Alberta, Canada - the world's richest hunting grounds for paleontologists. A creative dinosaur building competition pits the four of them against each other, and Sierra's broken heart actually helps her in building a very emotional dinosaur of betrayal. Alejandro faces his own challenge in the loser's spot. When Heather gets stuck in a big hole of her own making, he must chose whether to leave his biggest competition behind - or rescue the girl he cares most about. How inconvenient that they happen to be the same person!
