Andrew watches as Dobby and another house elf comes in greenhouse carrying a large flat rectanglar box warped in Gryffindor scarlet, on top of it is a smaller box in gold on July 31 at exactly noon.

Andrew nudges Aschere and tells her and the other Gryffindors to watch. Dobby sits boxes on Professor Phoenix's desk. He removes the smaller box then lid to scarlet box to reveal a cake that reads:
<span style='color:darkred'> Happy Birthday Professor Phoenix!!

Andrew slips Geraldine a note that reads: thanks for telling me!! Dobby had to work really fast to pull this one off for us. We owe him some cool socks.</span>
