An Island that is hard to reach sits two beasts who are not very fond of each other and jealous. They sit upon its beach looking back at each other.
The East Beast sits on the right side of the island while the West beast sits on the left side of the island.
The differences between the two beasts is that the East Beast appears to have webbed hands and feet and shorter hair, while the West only has furry hands and furry feet and longer hair.
The boy who appears on the island looks at the two and he decides that he assumed the west to be the worst while the east would be the best. He then decided that he likes the beast on the east the least.
In Dr Seuss Beginner Book Video version of this book, The west beast looks down feeling shy about how much the boy likes him better than the east.
