YMMV / Inai Inai Baa!

• Archive Panic: The series began in 1996 and shows no signs of stopping, meaning there are more than a good plenty of episodes to binge-watch (assuming one can find them all, anyway).
• Hilarious in Hindsight: The tape "Ohanashi shitai no daare?", from the Rina-chan era (1999-2003), contains a segment with Kuu meeting a ball named Pakupaku-san. Fast-forward to the Music Kingdom era in 2003, and this name is used for a character played by one of Wan Wan's hands.
• Memetic Mutation: It's been a meme to edit videos of the song "Guruguru Dokka~n!" (the second exercise song) so that an explosion appears when "Dokkan!" is yelled.
• Special Effects Failure: The Fuuka-chan version of the song "Omochi Mochimochi" used the same exact backgrounds and animation as the Rina-chan version of the song. As a result of the difference in height between the two actresses, the final product winds up having part of Fuuka's body being visibly cut off. It's especially noticeable every time the characters ask "Dotchi nano?".
