Loved for its funny and playful tone, How To Hide A Lion is a heartwarming and imaginative story about friendship. Youngsters can step into the paws of this cuddly character with the roarsome Lion 3D Mask - just add a yellow outfit to complete the look.
4. Oi Dinosaurs! by Kes Gray
Following on from the famous Oi Frog!, the brilliant Oi Dinosaurs! is full of fabulous rhyming fun and is a fantastic introduction to children’s favourite prehistoric pals. Take your pick between our T-Rex 3D Mask or Triceratops 3D Mask to create a dino-mite costume for World Book Day.
