Prehistoric Animals Break into US Parks

In this next adventure, the Watchers' destination is for Gee Creek Wilderness in the state of Tennessee, where there have been reports of great auks--penguin-like flightless birds. When they attempt to send them back to their time, the birds do not want to go back there. Even more unexpected, the Watchers end up in the time the great auks are from. They then get captured by Vikings, who work for none other than LM himself. There is also something Markie doesn't know that will be shocking and very surprising to him. Who will rescue the watchers from the villain's grasp?
