[He hears the sound and whips his head in the completely wrong direction to look behind them even as Baymax keeps an eye on where Naminé might be going. He isn't as aware of how the corridors work or anything so it doesn't immediately stick out to him as a possibility. The arena's full of weird tricks. He assumes it's something like that. Baymax blinks at the tree when he realizes what he had been tracking disappears.

It's when they both hear the surprised noise that the duo face the new tree and Hiro squints again to get a better look. It's hard to see who's up there, but he can hear her all the same.]

Hang on, we'll be right there! [Baymax moves to allow Hiro to crawl up onto his back and it's not long before the pair are up in the air, slowly soaring upward to align perfectly with where Naminé is. It's Baymax who sees her first through the leaves.]

These branches are not stable. [Hiro's frowning, leaning forward enough to push leaves out of the way to try and see inside said-tree.] There's probably somewhere better than a tree to drop you off if you're just looking to avoid the monsters.
