Mabel and Dipper return to Gravity Falls, and it seems that everything is the same as how they left it. However, Gravity Falls' mysterious nature comes back into play when Pacifica asks Dipper for help.

The Ice Tribes have left, along with the Phoenix. All seemed well, but Crooler wanted to finish what she started what seemed so long ago...take over Chima.

Laval was returning from a small expedition when he finds someone lying on the ground. Will Laval live to find out who it is, is the question.

When an astronautic mistake lands the space shuttle Avion in Chima, the men aboard wander off, yet Laval finds it. With the state-of-the-art Space Shuttle in the hands of a total novice, danger is afoot.

The Legend Beasts have returned. The Chi Falls have been restored. Nothing can go wrong when Laval and Eris test out a new Eagle jet...Or can it?

Eris begins to spend more time with Rogon. Laval feels odd and decides to keep an eye on their relationship. When Eris suddenly can't fly, Laval is suspicious.
