Change Nunu's name to Willump?
Nunu doesn't really do anything. The yeti he rides is what you are actually playing.
Willump uses all 4 abilities and the passive.
Willump laughs.
Willump dances.
In the Nunu Bot skin, Willump is all of the dialogue.
Why not have Nunu taunt, joke, laugh and even dance? Why not have Nunu lob his magical snowball at the target.
I get it, its Nunu the Yeti Rider. But you are playing as Willump and Nunu is just there.
Make the kid have more impact as the champion.
