How Creatures Move

The line walks on the padded paws
The squirrel leaps from limb to limb,
While flies can crawl straight up a wall,
And seals can dive and swim.
The worm, he wiggles all around,
The monkey swings by his tail,
And birds may hop upon the ground,
Or spread their wings and sail.
But boys and girls have much more fun;
They leap and dance
And walk and run.
