The Pillow is an item candidate for ssb4, based on the "pillow fight" activity. It's a multipurpose item and the second one to be introduced in Smash, the first being the Kirby's Parasol item in Melee.
How it would Work
1. the pillow could be used as a melee weapon
2. the player could crouch to rest their head on the pillow.
and 3. the pillow could be thrown to put any foes who get hit by it to sleep.
