It was just like Pinkie Pie to try to lure the bird (or birds) out with sweets. While Xion appreciated the sentiment, she didn't think it would work as well as it did with some people. At least whatever they were following made enough noise to actually be followed.

The dead end made her pause, though. If it was in the ceiling, the bird could have gone on, right? So why did it sound as close as ever, but she couldn't see it, even though nothing was blocking her view?
