This is the other 'Frosty', and it's pretty obvious why. Like the other 'Frosty', it's a natural form which has been propagated and circulated in the nursery trade. The frosty appellation was first applied to the other "frosty", so this one is - technically - the imposter. Confused? Yes, this kind of confusion isn't supposed to happen, but it does. Sometimes it's called 'Suave' to avoid the confusion, but this doesn't seem to have caught on. Maybe we should just take to calling it Frosty II, or...the other 'Frosty'!
