Beady Bold and the Yum-Yams: Monty's Island 2 by Emily Rodda

On a tiny island far away, in a sea that ripples with magic, Monty never knows what he might find... Everyone loves Bring-and-Buy Day, when Trader Jolly visits the Island with all the supplies Monty and his friends need. But this Bring-and-Buy day is different. Instead of Trader Jolly, there's a sneaky new trader called Beady Bold. And he's arrived with a boatload of trouble. The yum-yams are yummy, but they're hiding a very scary secret. All seems lost until Monty comes up with a daring plan. A charming and exciting series from beloved author Emily Rodda.
