Thank you everyone for your well wishes to Sean! He seems to be doing much better today. I suspect it’s because he had a much better sleep last night, which also means I was able to sleep better too! 
A while back I made Shaun the Sheep and the Naughty Pig into a sandwich bento (the tutorial here) so I decided to make Shaun and the Naughty Pig nori cutouts for musubis. It’s basically the same idea, you just have to make the cutouts smaller to fit your musubi.
I found a couple of pictures online and printed them out. Then using a good sharp scissors, I held the picture together with a piece of nori and cut out the outline of the animals. To make Shaun’s eyes, I used a hole punch to punch out the white part of his eyes and then used a smaller hole punch to cut nori for the black part of his eyes. It was really easy to do and you can apply the same technique to just about any picture you want!
