Whomping Willow

Yep, the Whomping Willow is still there on the grounds. Unlike other trees, this tree has an additude, and really, it's got a bad temper. The Whomping Willow doesn't like being hit, so basically it hits back, and it hits back hard. The only way to get to the Shrieking Shack, an old hideout used by some Resistance members, is to touch the center of the tree . It will instantaneously freeze for about a minute, but by the time it's able to move again, you'll be down in the Shack.
