Welcome to Moonbow Beach! The Rainbow High Shimmers are headed to the beach to get to know Rainbow World, and everyone in it, better! After learning so much about liquid rainbows and portal jumping, these besties could use a day in the sun. Jade is ready for a fun day surfing the waves and flying high in a kite! But her monkey is scared of the water and wants to play on the shore instead. Will they find a way to have fun together?
