It's time for the annual Wild Kratts Firefly Picnic so the brothers head off into the forest to find some fireflies to join the fun. But evil fashion designer, Donita Donata, has been capturing all the amazing flashing insects to use for a sparkly, one-of-a-kind dress. Will the Wild Kratts team be able to save the firefly population? They'll have to use everything they know and learn about bioluminescence and fireflies to save the day!
