From cute narwhals and octopuses to dazzling mermaids and seashells, this book features unique, intricately foiled designs that can be slotted together and to create 3D ornaments, hung up or threaded together to make a hanging seashell garland.

Each page is covered in blue foil, with foiled pieces which can be pressed out and coloured in to make a colourful collection of underwater-themed decorations. Press out the pieces, get creative with colour, then display your decorations!

Other titles in this fantastic series include: Birds, Easter Eggs, Butterflies, Unicorns, Christmas Decorations, Halloween, Flamingos, Llamas and Other Cool Things, Ancient Egypt, Dinosaurs and Chinese Zodiac.
