Pinky and Spiky are now in the hot air balloon. While they are travelling up in the sky, a question just popped in Spiky's mind. The birds, planes, helicopters, jets, butterflies, dove, and other flying creatures have wings and they can fly. How come the hot air balloon can fly high without wings?
Please help Spiky to answer the question in his head.
