Okay kiddo, Hufu is something that was created a long time ago to look and taste like human flesh, but it's not made with real human meat. It's basically a food product that pretends to be human flesh.
Now, I know that sounds really weird and creepy, but some people thought it would be funny or interesting to try and eat something that looks like us. It's kind of like a fancy dress-up game, but with food instead of clothes.
But don't worry, you won't be eating real people if you try Hufu. It's just made to look like human meat, but it's really made from soybeans and some other things. Some people thought it was neat to try because they wanted to see what it would be like to eat something that looks like us, but they don't actually want to eat humans.
Thankfully, Hufu is not very popular anymore, as most people think it's pretty weird to pretend to eat human flesh. It's much better to stick to yummy and normal foods like pizza and ice cream, right?
