Oslo and his wife Kristy both work in the kitchen. Kristy finished her work cycle a little ahead of Oslo, and while he was retrieving something from the fridge, she cleaned up the counter. Oslo came back to the counter work area, made the little Hmm sound that they sometimes make while working, and apparently started looking for his missing doughnuts. I guess he finally found them in the bottom cupboard because he got up and did the 'dance of joy'
