Mariopedia:Mini-wikis
From Mariopedia, a wiki on Mario, Yoshi, Wario, Donkey Kong, Super Smash Bros., and more!
Mariopedia currently has two mini-wikis hosted within it: Yoshipedia and Wariopedia, each with their own namespace, which cover articles from the perspective of the Yoshi franchise and the Wario franchise respectively.
For example, the Yoshipedia:Shy Guy article's History section is dedicated to games from specifically within the Yoshi franchise and its individual series, and it has a "Related appearances" section consisting of appearances, usually within the parent Mario franchise, where Shy Guys are directly associated with Yoshi or for appearances referencing Yoshi-related media.
