Description: While digging for roots, the Butlers and the Cave Dwellers see a Tyrannosaurus Rex running from the only thing it is afraid of - fire ants! These hand-size ants are swarming toward the Butler's cave. Lok runs to the villageĆto warn the tribe. The villagers try to get Lok to abandon his family while they run for the hills, but Lok runs back to his family instead. The village is surrounded by army ants. Gorak decides to hold the ants off by surrounding the cave with lit coal. The family digs for coal as fast as they can. Kim gets the idea of making a hot air balloon to take them to the top of the cliff where the ants won't come. They demonstrate the principle to the cave dwellers and they all start stitching hides together. Gorak goes to the cave of Giant Snakes to find enough snake skin to make a balloon. Lok and Katie go to the river to see if the fire ants have crossed the river. They watch the ants chew a tree down and cross the river on it. While John is figuring out how big the balloon should be Lok and Katie return to warn the Butlers that the fire ants are coming from two direction. John thinks this may have trapped Gorak in the cave of snakes and both John and Lok run to find Gorak standing on a tall rock. Lok lights a fire with flint and John and Lok use torches to drive off the ants and rescue Gorak. They race back to camp to find the balloon almost finished. Just then a lightning storm erupts while the ants are almost on them. Tana and Greg throw rocks at the ants to keep them from chewing down more trees to cross the line of flaming coals. John anchors the balloon everyone but Gorak and John climbs aboard. As it starts to rain Greg throws a grapple to the cliff as they pass. Everyone gets out and sends the balloon down for John, Lok and Gorak. Greg throws the grapple at the balloon as it passes but misses. John and Gorak are buffeted by the wind and the rain over the ants. Greg tries again with the grapple and this time John catches it. They pull them onto the cliff but the balloon floats away. Soon the ants have eaten everything and leave. The next day the family cleans up the camp.
