Adventure Time Time: What Was With Finn's Ear at the Macy's Day Parade?

Seriously, did they not fill up Finn's head all the way? Oddly, enough the ears fluctuated being filled. Can you make out the tiny Beemos carrying Finn and Jakes down the parade route for Macy's Day Parade?

Not sure if it's recent, but here's an Adventure Time float from Community State Long Beach's Auto Shop for their Christmas parade.
