The Little Mermaid Story Book Reviews
“The portable LEGO Little Mermaid Story Book set (43213) is suitable for fans aged 5 years and above and features two underwater environments inspired by the film – that can all fold up into a neat book. Firstly, join the Ariel minidoll in her hideout, along with Sebastian... More and Flounder and a collection of her land treasures. On the other side of the book, fans will find an Ursula minidoll in her leviathan cave complete with potions and mystery. The set also features a King Triton minidoll”

“Although the set may look similar to previous ones, the latest Storybook sets have actually had a design change. The case still acts as the play area and can be closed to become a book. It’s also still created by three unique pieces, two ‘covers’ and a spine, but there’s... More been a couple of changes. Firstly the covers have lost the small cluster of studs, which also means it’s lost the ability to connect the printed oval plate used in other sets.”
