Frog Canth

Kaerucanth (カエルカンス): A Frog Mecha Gigan with an electro tongue that is used by Monster and Zyuoh to spread a deadly virus across the city. As the others use Bio Robo to fight the Mecha Gigan, Hikaru nearly gets herself killed to find the flowers needed to synthesize an antidote. After arriving, with Yellow Four backing her up, Pink Five installs the antidote into Bio Missile to before Bio Robo fires it into the exhaust pipe that the virus is expelled from. With the monster's primary attack disabled, Bio Robo destroys the Mecha Gigan.
