While everyone was sailing on the ship, they had noticed they had forgot Eustace at the island. Eustace had not known where they had gone and looked for them on the island.
Eustace fell into a forest and witnessed an old dragon dying as he stood up. He saw where the dragon was coming from and saw all the gold and treasure that was in a cave. He put a bracelet on and turned into a dragon overnight, mostly because of his jealousy and greed.
My shoes! They're GOLD!!!That means that statue was...
In the middle of the night, Eustace (in dragon form) hears a voice in his head saying to go to a well. He goes and finds a huge lion (Aslan) telling him to go down into the well and bathe in it. He does so and when he gets out, he becomes a boy again.
All aboard the Dawn Treader!
The Dawn Treader has a surprising encounter with a sea serpent and everyone was scared of it. Lucy and Reepicheep even fainted. But Eustace remembered how much of a brat he was to everyone and decided he was brave enough to take on the sea serpent himself.
Caspian, Lucy, Edmund, and Eustace docked the Dawn Treader at an island to stock up on supplies. They see something fall into a lake and went to go check it out. It looked like a gold statue. So Edmund fetched a spear to try to lift it back up, but let go of the spear because it seemed to heavy. While doing this, Edmund had accidentally dipped the front part of his shoe in the lake and it turned gold. He wondered if the staue was once a real person. Or maybe one of the seven lords?
They leave the island. They named it DeathWater Island.
