Party
Baymax is amazed by the party. The music sounds so much better than when filtered through a digital brain. He can feel the rhythm and the bass, and even tried dancing a bit (moving somewhat ridiculously but genuinely happy to be doing it).
The lights are pretty and the music is great, but after a while, he notices the pretty lights from the Christmas decorations Strange had noted. He starts moving farther from the party in order to examine the decorations, not realizing he's wandering as far as he is.
