It's Shani's birthday and Polly, Lila and Nic want to give her the best gift by recreating her favourite, discontinued candy -- the Queen Worm. During a tour of the local candy factory, Polly, Lila and Nic sneak away and go pocket-sized so they can gather the ingredients. But being pocket-sized in a candy factory leads to sticky situations. With the taffy-pullers, chocolate-melters, and pretzel-twisters standing between them and their sweet goal, Polly will learn that making new memories can be better than reliving the old.
