- Neptunia's tall and thin design was inspired by one of Wanda's original concepts.
- Originally, both Neptunia and Astronov were going to have orange hair and eyes before WikiaIvan1997 changed it so that they look different.
- Unlike Cosmo, Neptunia went to Spellementary School, but she barely passed, which is likely an explanation for how she can't control her magic half of the time.
- It is revealed a few times that Neptunia is smarter than Cosmo, making her the third dumbest person behind Cosmo and Timmy's Dad (fourth after Tony was introduced).
- Neptunia is a fan of All My Biceps, like Jorgen.
- Neptunia is allergic to styrofoam, as seen in "Spouse Swapped!".
