Plagiarizing Google

Verses 1 and 2 of my dance song were done. Only the last verse stood between me and completion. A piece of imagery came to me: a cocoon made of sound. "Cocoon of sound" wasn't going to scan correctly, though. "Cocoon" needed to go at the end of the line.

I thought of this:

I feel a strong vibration
Here in my sonical cocoon

Was "sonical" even a word? Probably didn't matter. It had the right number of syllables, and everyone would understand what I meant if I added an extra "al" to "sonic." Still, now I was curious. Real word or not? I googled it.


Hey, wait. What's that second one?

I feel a strong vibration
Here in my sonic wall cocoon

Does that count as plagiarism? Or can I call it found art?
