why are opal fruits so damned addictive?

Then what are American Mars bars like? And what are British Milky Ways?

 

I had to wikipedia this one honestly as i don't remember exactly what American Mars bars were like (they don't sell them anymore).

Mars Bars stopped being sold in the US back in 2000. They were plain nougat, almonds, caramel and covered in chocolate. You can no longer buy a candy bar called a Mars Bar in the States.

A British Mars bar is what the Americans call a Milky Way. Apparently, as I just found out off a wikipedia. It is called a Milky Way in Europe as well. They are just like what you get over here as a Mars Bar. No difference from what I can tell.
