How to Be a Pirate — Cressida Cowell

SKULLION

COLOR: Black and purple
NASTY BITS: Vicious teeth and claws
THREAT TO VIKINGS: Watch out or it will eat you!

The savage Skullion can't see, hear, or fly, but its keen sense of smell can easily sniff out a Viking snack. And it's not a dainty eater!

When Hiccup finds a coffin at sea, he opens it to discover the hook-handed Alvin, who tells him a riddle that will lead to the treasure of Grimbeard the Ghastly, the world's greatest pirate and Hiccup's ancestor. Setting out on a treasure hunt, Hiccup and his friends must master the art of swordfighting! How else will they escape an island of homicidal dragons, defeat a boatload of Viking pirates, and survive a dirty double cross?
