Using Mantara is easy! First, if you want to use his 'Water Blast Attack', just fill his head with water. Then, give it a squeeze and watch a watery blast come out of his mouth. Kids can also have fun stretching Mantara up to 3 times his size (up to 20''/ 50cm). When you're done stretching, he'll go back to his original shape. As for maintenance, keep Mantara away from sharp objects that could tear his body and let the water dry out if it's inside his head. Also, don't expose him to extreme temperatures. Have a great time playing with Mantara and collecting all the other Heroes of Goo Jit Zu Deep Goo Sea figures!
