Wings, ears, tails

It’s the year 20##, and something happened overnight. The night of new year’s, when everyone goes to sleep, they gain animalistic parts. Those older than 70 do not get any, and those younger than 10 don’t get any. 80% get wings, with 10% of those getting multiple sets of wings. 80% get extra sets of ears on their head, with 10% of those getting multiple sets of extra ears. 80% get a tail, with 10% of those getting multiple tails. Wings come in feathered 60%, scaled 30%, insect like 9.9%, and other 0.1%. Ears come in furred 60%, feathered 30%, scaled 9.9%, and other 0.1%. Tails come in furred 60%, scaled 25%, feathered 14.9%, and other 0.1%. Most get some combo of these. Nobody knows how to use them at all when they first get them. They are sensitive. All who got multiple sets can swap them out with the ones not out becoming tattoos on the body.
