Pool Party Mundo's Ukulele only has 3 strings!

Ukuleles [typically] have 4 strings. In the splash art, Mundo's ukulele has 4 strings, but his in-game model has only 3 strings!

Please Riot, fix the model for the ukulele! It's a small detail, but any ukulele player out there will notice this is all wrong.
