The tiny Tindims are like the Borrowers-on-Sea, who turn our everyday rubbish into treasure. Mother-and-daughter duo, prizewinning Sally Gardner and Lydia Corry, create a fun new world of characters and adventures in their empowering new series for 5-8 year olds inspiring conservation and inventive ways to recycle.

In the fourth Tindim adventure, a glow-in-the-dark squid, drawn by the light of the moon, has wandered far from its friends on the ocean bed to the lake on Rubbish Island. The Tindims are puzzled by their new shiny lake, but with the help of Spokes, Barnacle Bow and a rather special invention, they discover the squid and try to help it on its way home again.
