Mystery only partly solved

[vvvexation]

Apparently that bike horn that I've been hearing across the street most afternoons doesn't belong to a small child as I'd assumed, but to a guy walking down the street with a shopping cart that has bags of something orange hanging from it. Presumably he's selling the orange stuff, and thus using the horn in an icecreamtruckish fashion (I have to say, I rather prefer even crappy music to this more distracting honking), but from this distance I can't figure out what on earth it might be. Cheesy popcorn, maybe? It's the right size but the wrong color for cotton candy.
