Ep26-The Invisibble Robeast

Haggar uses a spell to grant a powerful robot fighter invisibility. On their way back from the fruit-market, Allura, Lance, Pidge, and Nanny have their carriage forced underwater by it and Allura is nearly captured. The Voltron Force attempt to find a way to defeat their unseen enemy - and even after they bring it into view long enough to note its strengths and weaknesses, they learn the hard way that one of its major benefits is one of their greatest hurdles: water.
