I guess technically these are not onigiri as they have no filling. I searched high and low for my sweet bean paste but couldn't find it and my girl is not fond of turkey which is the only meat in this house right now.
About the macaroni and cheese balls; they were a flop. She didn't like them at all. I asked her if she tried them with ketchup and she said "Oh, is that was that was for?". I love that kid.
