So he gave a sudden leap and leaped full upon the back of the great dove.

Then began a desperate struggle.

The dove was as strong as Ugu had been, and in size it was considerably bigger than the Frogman.

But the Frogman had eaten the zosozo, and it had made him fully as strong as Ugu the Dove.

At the first leap he bore the dove to the floor, but the giant bird got free and began to bite and claw the Frogman, beating him down with its great wings whenever he attempted to rise.
