Forgotten Realms 2012
While unhatched, Bubbles’ egg was stolen by a tribe of kobolds, who had the intent of raising him as a champion for the tribe. The kobolds did not realize how intelligent or strong dragon are, even at birth. Shortly after hatching, Bubbles forced the kobolds into servitude, using them to raid Loudwater and bring back items for his hoard.
Since his egg was stolen, he was never given a proper name, and Mouzer dubbed him Bubbles.
While investigating the kobold raids, the party defeated Bubbles in combat, but allowed the dragon to live. In exchange, the dragon gave the party his accumulated treasure and promised a favor at some point in the future.
His location is currently unknown.
