Blow up your inflatable, apply the factor 50 and polish those sunnies... Mira and Dave the naughtiest unicorn are going to the BEACH! Mira can't wait to build a GIANT sandcastle (although Dave is more interested in eating a GIANT GLITTERY ICE-CREAM). But when Mira and her Unicorn School friends go exploring and spot a little narwhal in BIG trouble, the fun day out turns into a super-adventurous rescue mission...

it's Dave and Mira to the RESCUE!
