Happy home paradise?

I would have no idea why that is. But I would say you or who ever may have a credit card linked in your switch should check some usage records on that card. A few clicks at the right time and u just bought some product. Or u had it and didn't know. Other than that I have no idea

Hhp is for sure a paid dlc add on. Idk how you would get it without paying the online membership. Only thing I can think of is someone else hacking ur account to purchase it using your credit

I'd agree unless you bought acnh download with it already attached in the package offer.. and have just got to the stage of unlocking it.. 🤔

I agree with Eliza
