Now wait for your trouble meter to empty, hop out of the tree, walk over and have a look up her skirt. All the other girls wear white underroos. Nail them with a projectile from afar and quickly hop in a trashcan before you’re seen. When your trouble meter dies down, go have a look.
Even Ms. Danvers (Crabblesnitch’s secretary) fancies white underwear. When she grabs you for being naughty, stomp her foot and take a peak while she’s hopping up and down.
