As Rudolph and his friends search for Happy (who left after his hat accidentally fell off saving a baby Pterodactyl and revealing his big ears, causing the dinosaurs to laugh), they repeatedly encounter Eon.

The group then travels to the island of 1776, which reflects Colonial America and is ruled over by "Sev" (AKA 1776) who resembles Benjamin Franklin.

Managing to melt his way free using his nose, Rudolph climbs up to Eon's nest where he finds Happy, who refuses to leave.

At the sight of Happy's large ears, Eon bursts into uncontrollable laughter which sends him tumbling down the side of the mountain and into the three remaining snowballs, freeing O.M., 1023, and Sev.
