"You're right... I don't get the reference. Why would anyone use breadcrumbs? That seems, a rather odd choice." That was going to be something for him to ponder for a while if it didn't get explained.

The screech of the bats has Skyfire fluffing his wings and moving them to protect Tsukishima if needed. All he'd have to do was flatten himself against Skyfire's back to let them cover him fully.

When it came to the bats, Skyfire started to growl and swat at them with the fluffy end of his tail, trying to drive them off without hurting them. He'd actually attack them if they didn't back off, but he figured that they were just startled... how true that was though was up for debate. Until they did more than screech at them, he'd keep his actions defensive and non lethal.
