Diego and his friend, Billy the Beaver, are in the Canadian Rockies helping all of the river animals keep their homes safe from an overflowing river! But uh oh! Alicia calls on the video watch - A Giant Wave is coming down the river and headed to Billy the Beaver's family! It's going to be a tight race against the Giant Wave as we go down the Water Slide and help Billy roll some stray logs to make a dam around a frog families' river home; chomp with our sharp, orange beaver teeth to free a baby deer caught in some prickly river bushes; and do a super-jump with our Rescue Pack kayak to reach the beavers' dam just in time! It's going to be a close race! Will we beat the Giant Wave?
