"The Brain Parasites"
The FF are called out to a camp ground where strange creatures have been sighted. Once there, they find strange prehistoric creatures terrorizing the campers and the locals. When they get close, the creatures mysteriously explode. The FF investigates as they find out that a meteor that crash landed near the camp carried a strange creature that has the power to transform living creatures into prehistoric dinosaurs. Things get worse when Sue is taken over and it is Franklin who saves her before she explodes. But before Sue is rescued, she manages to lay eggs for the creature.
