What is the Supernova candy bar?

There isn't a candy bar called "Supernova" that is widely known or commercially available.

It's possible that:

* It's a local or regional candy bar: Perhaps there's a small, independent candy maker who produces a bar with that name.

* It's a fictional candy bar: Maybe it's mentioned in a book, movie, or TV show.

* You're misremembering the name: It's possible you're thinking of a different candy bar with a similar name.

Could you provide more context? For example:

* Where did you hear about this candy bar?

* What kind of candy bar are you thinking of? (chocolate, caramel, etc.)

With more information, I might be able to help you track down the candy bar you're thinking of.
