Happy Amumu Skin

I've looked through all the amumu skins, and I love him to death. Got to play him today and considering SR'ing (which is a big thing for me lol), but we've had the poor mummy for 9 years and he's never once been seen smiling, not even at his own surprise party. Can we maybe get a happy amumu skin? (Yes I know, it breaks his entire lore, but I think that would make it ironic just the same) I'd love for it to be legendary tbh. Just a thought.
