Allie and the Monster Who Said Blah Blah Blah

Allie has a monster problem. A monster is preventing her from sleeping, terrorizing her with his scary "Blah Blah Blahs" that sound like the incomprehensible things that adults say (often recognizable to parents). Her mom helps to solve her problem with a magic book that causes the monster to shrink and go away. But Allie's problems are not over yet. No longer bothering her, the monster seems to be threatening her parents in their bedroom. Allie takes care of the monster herself this time, in a surprise ending. (Hint: it has to do with the TV.)
