Crumble cakes! Mr Tiger and Betsy join Myrtle the mermaid to listen to tall tales from her world beneath the waves. There may be monsters... shipwrecks, lost treasure and secret cities. But what happens when a tiger's whiskers and tail are simply too long to squeeze into forgotten dark caverns where even the moon cannot shine, and Betsy has to take the final steps of the adventure on her own?
