“ The blue foam spread quickly, and had almost entirely enveloped the room, moving rapidly towards the last clear door, when suddenly the door burst open, and Simon, looking flushed, and panting heavily, stepped into the room.“Nooooooo!” shrieked Maven Ellie; a shocking sound out of the usually calm and cheerful magician. But it was too late.The foam, already covering most of the room, seemed to stiffen for a moment, before a molten red glow began to take over. The foam hissed, as though in anger, and at an alarmingly fast rate, it raced towards Simon, who had frozen obligingly, the moment Maven Ellie had screamed.A look of terror crept over his face at the sight of the crimson foam racing towards him. Desperately, he tried to move away, but the foam had already reached his feet, and he was stuck fast. Maven Thom, in a rather stunning display of athleticism for a man of his age, made a running leap for the small space that remained between Simon and the door, just barely clearing the approaching foam. The foam continued to climb up Simon’s legs and chest, covering his neck and face in seconds, until he was completely encased in the hardened foam. ”
