This is an enchanting story that teaches children about the importance of protecting the marine environment. Elly and his friends visit the seaside and build a fantastic sandcastle on the beach. They use all sorts of plastic objects - a bottle, a straw, an ice cream wrapper - to decorate their castle. The following day they find it has all been washed into the sea…….

"This lovely books brings the perils of plastic to life through a child's eyes, but gives back the real delights of the seaside with a genuinely feel-good finale." Marine Conservation Society, UK
