How to buy frog wif hat?

Excuse me, I'm a bit confused here. Could you please explain to me how to buy a frog with a hat? I've been hearing about this odd transaction lately and I'm really intrigued. Is it a real thing or just a joke? If it's genuine, could you guide me through the process? Where do I find these frogs with hats for sale? Are there any specific platforms or marketplaces for such exotic purchases? Also, do I need to have any special skills or knowledge to complete the transaction? I'm a newbie in this area, so your advice would be greatly appreciated. Thank you in advance for your help!
