These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Jelly Jamm
Bizarro Episode: The "Flying Bathtub" episode is notably weirder than the other episodes, and breaks the normal formula: Unlike normal episodes, it's Bello and Mina who have a wacky adventure together, not Bello and Goomo. There's a rap sung by the voice actors, not a pop number by Guille Milkyway like usual, the plot revolves around a literal flying bathtub and a brief scene involves a tap-dancing basketball.
Ear Worm: The theme song WILL get stuck in your head.
Les Yay: While you can interpret Bello's and Goomo's close relationship as just a friendship, it's really hard to deny the subtext between Mina and Rita in "Home, Flying Home", which included Mina moving into Rita's house for a while, them spooning in bed and Rita undressing Mina in her sleep to wash her shirt. What follows is them trying to live a week together, which goes horribly because of their different lifestyles. After getting into a big fight, Rita discovers that Mina tried the whole week to make a tea that changes colours specifically for Rita, and Mina realizes that despite their differences, she really likes Rita as well. They decide to spend another week together as roommates.
