It’s movie night at the garden house, and Mia and Paula are watching a sappy romance, much to Vincent’s disgust. He’s even more disgusted when Mia starts talking dreamily about Prince Mo – right in front of a confused Paula. As their bickering heats up, Mia finds herself needed in Centopia. A severe drought is afflicting its citizens, thanks to Panthea’s wanton destruction. To stop her reign, they must redouble their efforts to rebuild the Trumptus and free the captured unicorns.
