Her idol is a pillow. Her tentacles are twisted bed sheets/blankets. Her W causes feathers to fly when she hits. Her E debuff is a bunch of 'Zzzz's streaming off the target (or something similar to signal fatigue -- the bed sheets/blankets hitting vessels are trying to get them to go to sleep). She has like a bed sheet/blanket around one arm over her pajamas. Her E uses that to pull out Spirits.
Chroma skins are similar to Meowkai with different themes and colors.
I just want the big mama of top lane to get a nice skin, so I'm up for anything.
With curlers in her hair and wearing a night gown?
Obligatory Sleepover

This is one of the best and funniest ideas I have ever read on the forums. Really great idea man !!!
Reminds of another skin concept http://fc06.deviantart.net/fs71/i/2013/260/b/8/pillowfight_shyvana_by_vaejoun-d6mof9l.jpg

I don't even play Illaoi but she definitely deserves a fun skin like this!
I'd prefer a cool skin first than a funny one.
Im literally down for ANY other skin.....
sounds good though.
Could go in line with Ragdoll Poppy even?
