Ep33-Attack of the Fierce Frogs

Haggar creates many miniature-robots disguised as tadpoles to invade Arus since they will thrive in water which Voltron would otherwise not wish to enter. Two siblings collect some to study at home with Pidge's help, and he takes some himself. That night, a group of mutant amphibian-like creatures attack a ship and the children's home. Though they easily destroy the ones in the castle, the Voltron Force's attempt to destroy those out at sea proves more than the usual challenge when a larger robot arrives as well, and damages the Green Lion so Voltron also leaks when formed.
