List of Wondermation April Fools' Jokes

=== 2022 ===
On the morning of April 1st, 2022, an announcement would be put out on audiences' TV, that said that every Wondermation show airing at the moment would be cancelled, in favor of the Gustavo series, and that Wondermation would be renamed to "The Gustavo Channel". The reason, as mentioned in the announcement, was that due to the popularity of the show compared the other shows, and also because of budget cuts.
After the announcement was over, reruns of random Gustavo episodes from Wondermation: Phase 1 would air, 24/7, with some extra content to date too. However, after April Fools' was over, Wondermation airing would go back to normal.
