- Alternate Aesop Interpretation: As mentioned on the main page, Nina's catchphrase of "Now I know: Don't wait to go!" makes less sense when you consider she only waited because she legitimately didn't think she needed to go earlier. A better Aesop for that context would be "If you know your bathroom break opportunities will be limited later, it's better to go earlier when the opportunity presents itself, even if you don't necessarily have to", and Nina's catchphrase would still make sense.
- Author's Saving Throw: After people complained about Nina suffering from Aesop Amnesia, and always sending the Family-Unfriendly Aesop on waiting until the last minute to use the bathroom, season 3 changes things up by having her just learning about good behavior in general in different locations, like how to act in a museum or in daycare. She's also shown to be less stupid and more innocent and naive.
- Germans Love David Hasselhoff: This show is big in Japan compared to the rest of the world, possibly because of the country's respect for hygiene and bathrooms in general. There's even reports of parents saying that this show helped toilet train their kids as opposed to them learning the Family-Unfriendly Aesop mentioned above.
YMMV / Nina Needs to Go!
