Someone Help Out A Uke Noob?

Hey so I just got my first uke and I am starting to get the hang of it and get interested in trying songs. I watched this video on how to play Float On - Modest Mouse. I understand all of the chords, but it is pretty hard to see what strings the guy is playing and in what order, it looks like a pretty easy song but I need a lil help. Thank You

If you're talking about the arpeggio chorus part, he's picking the C E A E strings in that order over and over.
