We just thought that it's summer and fair/theme park season so cotton candy would be a nice tie in. Also the colors are very photogenic. My wife had the idea of adding the edible glitter and butterflies for that extra touch.
You can find the Cotton Candy Churros at the Naughty Churro stand, booth C12, at the 626 Night Market.
Don't name drop us though. He'll charge you extra.
