- Alternate Character Interpretation: Sandy berating SpongeBob for getting an abrasive side. It's meant to give a Be Yourself message, but considering the fact that SpongeBon was an Extreme Doormat prior to buying it, this could be seen as Sandy telling him to let people like her walk all over him.
- Informed Wrongness: At first. Prior to becoming an outright antagonist, the abrasive side was treated as a big jerk for his treatment of SpongeBob's friends. While Patrick and Squidward didn't really do anything to deserve it, Sandy and Mr. Krabs did: Sandy tried to use SpongeBob as a guinea pig for one of her new inventions without even bothering to ask first, and calling Mr. Krabs out on his cheapness is hardly a bad thing.
