During 2019, The Loud House gained an ad in Nickelodeon Brazil named "The Louds" (Os Loud)
There aren't lots of evidences, but part of it was found by Lucas Macieski de Loreto
The ad uses fragments of the episode "Ties That Bind", it is possible that the Latin American Nickelodeon also aired this ad (in spanish duh)
