After the explorers find the mushroom forest a resting Professor Lindenbrook wakes up to find Count Saknussem has ordered Hans to chop down several mushrooms in order to buid a raft. Lindenbrook goes off to confront Saknussem only to find him at the shore of a great underground sea. At that point the two men are attacked by a "dinosaur" and run back into the cave. An instant later they run back out with the rest of the group dragging the raft which is already BUILT AND PACKED!

As the dinosaurs attack again watch how Madame Goteborg trips OVER the rope while running away but it is wrapped AROUND her ankle several times in the very next scene.
