The Founding Babbies is the name given to the 18 teams formed after the 2012 4chan Winter Cup. The Founding Babbies were the third wave of new teams, and the largest mass founding to date. Due to the prodigious amount of new clubs, the 4chan Cup Committee introduced the Babby Cups to serve as a relegation league for the 4chan Cup. Each of these teams would compete in the 2012 4chan Spring Babby Cup alongside four other teams remade after the Second Founding, for the right to move into the Top Tier.
