It sprang to life at once; long, prickly, bramble-like vines flew out of the top and whipped through the air. One tangled itself in Hermione's hair, and Blaise beat it back with a pair of secateurs; Daphne succeeded in trapping a couple of vines and knotting them together; a hole opened in the middle of all the tentacle-like branches; Hermione plunged her arm bravely into this hole, which closed like a trap around her elbow; Blaise and Daphne tugged and wrenched at the vines, forcing the hole to open again, and Hermione snatched her arm free, clutching in her fingers a pod just like Longbottom's. At once, the prickly vines shot back inside, and the gnarled stump sat there looking like an innocently dead lump of wood.
