This is one of those moments when I wish I'd been filming me and my sis's commentary while watching:
Draco: *Notices how almost all the booby traps involved spikes* OH! I know what this is...There's gonna be a wall with spikes closing in on him! Me: *Thought about a giant golf ball* Or we just played the Indi-A trap card! Both: *Boulder shows up* LOL! We should be filming our commentary!
