Tiga Whicabim loves her new life in the witchy, glitzy, black and white world of Sinkville. Now, suddenly, colour has started seeping back into Ritzy City – first there was a green apple in the middle of the road, and then Miss Heks reappeared in a garish orange dress. Tiga is very suspicious. But Miss Heks is only the tip of a very witchy iceberg. As Tiga, Peggy, and Fluffanora soon discover, all the Big Exit witches are back! And they want to destroy Sinkville once and for all.
