Bonjour!

I am confused on a couple of adjective forms-> mou and fou. Can you spell out the plural forms for masc and fem for these two? ex: soft couches, crazy scenes, etc

Here you go:

Il est fou, il a un fol ami, Il a des fous amis.

Elle est folle, elle a des folles amies.

And mou works just the same.
