Can you buy a paal on Kraken?

Excuse me, I was wondering if you could clarify something for me. I came across the term "paal" in relation to cryptocurrency trading, and I'm wondering if it's actually possible to purchase one on the Kraken exchange platform. I've done some research, but I'm still a bit confused. Is "paal" a specific type of cryptocurrency that's listed on Kraken, or is there some other meaning I'm missing? Could you please provide some clarity on this matter? Thank you in advance for your help.
