Can I buy bells with real money?

Excuse me, I'm a bit confused about something. I came across this statement that says "Can I buy bells with real money?" and I'm wondering what exactly is being referred to here. Are we talking about some sort of virtual currency or tokens within a game or platform? Or is there a specific type of bell that's being sold for real-world currency? Could you please clarify and provide some context for this question? I'm really interested in understanding the nature of this transaction and whether or not it's a legitimate practice. Thank you.
