Pop culture references are essentially one giant communal joke that everyone is in on. MaraPets is no exception to this, having various stuff on the site pay homage to varied elements of pop culture. From the obvious to the obscure, these Maradans have something for everyone.
Unless the joke is otherwise explained, reference links will take you to the related Wikipedia/Fandom page.
"Welcome to the Jungle" by Guns N' Roses
Popstar - Could be referencing Katy Perry (especially with the dress)
Flitterbug Hits - Called "Gary Flitter" in its file, but that name remains unused due to Gary Glitter's paedophilia case causing him to be a "public hate figure" in the eyes of British people.
