Sir Scallywag and the Golden Underpants - Andreae, Giles

When King Colin's golden pants go missing, he calls for Sir Scallywag, the bravest knight in the land. But . . . Sir Scallywag is only 6 years old and with an evil giant to pursue, it's nearly mission impossible! Luckily, it's a story of David and Goliath. With his trusted steed Doofus at his side, Sir Scallywag proves that even the unlikeliest hero can be the bravest knight of all.
