What happens when bud tries to catch the train with bugs in Bud Not Buddy?

Bud throws his suitcase to Bugs (already on the train) and Bud starts running for the train when suddenly his blue flyer flys out of his suitcase, so Bud stops to try to catch it and it magically lands in his hand, because the flyer fell he missed the train and Bugs threw back bud's suitcase, and went on to Chicago.
