Where can you purchase the powerhouse candy bar?

It seems you're asking about a candy bar called "Powerhouse". Unfortunately, there isn't a candy bar with that name that's widely known or available commercially.

Perhaps you're thinking of a different candy bar, or maybe it's a local or regional treat. If you can provide more details, I might be able to help you track it down!

For example, do you remember:

* Any other details about the candy bar? (color, shape, ingredients, wrapper)

* Where you might have seen it? (store, region)

* When you might have last seen it?

Let me know and I'll do my best to find the Powerhouse for you!
