What's Huck's first plan to get the money back for the girls?

Huck goes to the King's room and hides when he hears the Duke and King approaching. The conmen debate whether they should leave now that suspicion has been raised or wait until the rest of the property is sold off. They choose to stay and hide their money in the straw tick mattress. Huck steals the money immediately and waits until it is safe to slip downstairs to hide it.
