Jeffy is the most popular and most hated character in SML
Brooklyn T. Guy Has appeared in the most episodes than any other characters
In February of 2021, the show was rebranded when Logan was given a cease and desist by Nintendo for using the plushies of Mario and friends in videos inappropriate and offensive, thus using the puppets Logan had made a year and a half prior from that day onwards. Every channel containing Nintendo was deleted, but there are users who downloaded them and reuploaded them on YouTube.
There is an extremely popular theory that once a video ends, the timeline resets in the SML universe as there's little to no character development and every character acts like they have had a fresh start at the beginning of each video.
This Series is on Logan Thirtyarce's YouTube Channel Supermariologan.
