Harry Potter and the Chamber of Secrets PC 100% Walkthrough - Part 11: Spongify Challenge

This is it. The final spell lesson granting us complete mastery over the secrets of Hogwarts! Before that however, Harry is determined to discover the secrets of the challenge itself, and afterwards, master the time trial before moving on.
Considering the sort of hazards in this challenge, I can come up with far more impressive titles for Harry than the "Boy who lived".
How about Hammer dodger? Or what about Owl Opener? Imp Impersonator? And finally, what about the long deserved "Combustible-Hemorrhoid-Asscrack-Enchanter?"
