On a far away planet, Deceptitran the Decepticon ruthlessly enslave the planet people known as the Tlalakans. When the slaves rebel against their evil master, he sends a distress signal to the Decepticons, which the Autobots intercept. Seaspray, Bumblebee, Perceptor and Cosmos fly to the alien planet to investigate. As soon as they land and learn of the situation, they take sides with the rebels. The Tlalakans reveal the Autobots their fascinating secret: the Well of Transformation, a pool of water which allows them to take on any form they wish, like merpeople. During the battle against the Decepticons, Seaspray and Alana the Tlalakan fall in love, despite the difference in their outer appearances.
