League of Legends needs a "Hey waiiiit!" emote for Yuumi.

Emote would feature Yuumi with an outstretched paw and a desperate expression.

For those situations when someone spots a juicy bait and you feel the need to commit to trying to save them in the inevitable collapse. Or when your ride passes just outside of warding range of a bush so you hop off to drop the ward only for them to continue running through un-warded territory without letting their support catch back up. Or when you get caught out and there's an ally just out of reach nearby who could rescue you if they just stopped running for half a second.
