Trivia

 * The majority of the clips that can be seen in the trailer are taken from the third episode, "Spring Broken", the fourth episode "C.H.E.R.U.B", the fifth episode "The Harvest Moon Festival", the sixth episode "Truth Seekers", and the seventh episode "Ozzie's".
 * Except for the seventh episode, all the episodes' synopsis provided by their YouTube descriptions all end with "things sure do happen".
 * The previews showed during the BLM Helluva Charity Stream were Blitzo reprimanding Moxxie for accidentally setting fire to his office from "Murder Family", Moxxie and Millie's conversation about Loo Loo Land in the episode "Loo Loo Land", the C.H.E.R.U.B Jingle from the episode "C.H.E.R.U.B" and Stolas and Blitzo's conversation regarding the Harvest Moon Festival from episode of the same name, respectively.
 * Additionally, "C.H.E.R.U.B" was initially supposed to be the third episode of the first season, as revealed in the description of the BLM Charity Stream, with "The Harvest Moon Festival" being the fifth and "Spring Broken" presumably being the fourth.
 * While it was in development, the sixth episode promised to be the longest episode in the season, which took longer to produce. Specifically, by an extra month.
 * The episodes "C.H.E.R.U.B" and "Ozzie's", respectively, are dedicated in memory of those who were affiliated with the series: Adriana Margarita Rodriguez Hernandez, the mother of animator Adolfo Rodriguez, and Steven "LemonyFresh" Dorian, a clean-up artist for several episodes.
 * The season was initially planned to have eight episodes in production, with episodes seven and eight being the two-part season finale. However, it was decided that "Ozzie's" would be the final episode of the season, with the eighth episode serving as a standalone special, due to production delays, technical difficulties and pertaining legal issues.
 * It was also stated that episode 7 was the "real story finale of the season" and further explaining that episode 8 was created as a bonus episode, anyway.
 * According to Vivienne, episode 8 is "very much spectacle", with a simple story as a direct follow up to another episode, and in a reply to a question about how the continuity may have changed without the episode releasing when it was supposed to, Vivienne states the episode just exists on its own and will fit in after Ozzie's.
 * From the episode "The Harvest Moon Festival" onwards, the episode thumbnails no longer have the episode titles on them.
 * "Truth Seekers" is the longest running episode of the season, lasting twenty two minutes.
