14 - Mario has a Castle. He also has a house that he shares with his brother that can change its outward and internal configuration without any sort of construction required.
15- Mario was once a carpenter under the alias Jumpman and dated a blonde woman named Pauline who was kidnapped by a gorilla named Donkey Kong and a battle/chase ensued over a construction site of all places.
16 - After defeating said gorilla, Mario/Jumpman caged the gorilla and sent miniature alligators, electric balls of death and various flying birds after the gorilla's son, Donkey Kong Jr, who had set out to rescue his father from a zoo, an electric room of death, and the old construction site where Jumpman and DK first fought. Also, Jumpman dies but somehow gets better.
17 - He then dumps Pauline and disappears for awhile.
18 - Years later he reunites with Pauline (as friends), with Pauline having somehow in the time since they last met turned from a blonde into a voluptuous brunette. The son of the original Donkey Kong (DK Jr), now going under the name of his father, kidnaps Pauline, forcing Mario to rescue her across another construction site, a forest, a lake and other environments.
19 - Mario and DK at some point after the previous entry become buddies and start their own toy factories, with windup toys of themselves that are presented to Pauline.

This happens several more times, with additional toys added of Mario's brother Luigi, a princess and a mushroom man.
20 - Mario has the craziest and most dangerous of recurring parties that he invites his best friends and worst enemies to.
