Shawn Packer

Shawn Packer is the secondary protagonist of the second SlappyWorld book, Attack of the Jack!, and is the brother of Violet Packer, the main protagonist.

History
Violet and Shawn Packer live in Yellow Springs, Ohio. They are going to Sea Urchin Cove, where their Uncle Admiral Jim lives. Shawn is said to be playing Battle Soccer on his phone while they are on the bus. A couple minutes later, they are in the small village and he smells the ocean air. He and his sister walk in plains and find a black cat, which Violet thinks is good luck. Then they look around once they reach the village, looking for something to eat for lunch. They then meet a lady who they talk to, but strangely she says to never enter their uncle's lighthouse.

They find their uncle's lighthouse at the beach, and they go inside. Shawn then sees the black cat again, which very strangely, calls out to Uncle Jim that he has visitors. A big, scruffy man then comes down the rickety stairs, which at first Violet and Shawn don't realize is their uncle because of how old and big he is.

Jim then welcomes them and they quickly ask him about the talking cat. He reveals this is his pet cat, Celeste, which keeps him company.

After a while they are done unpacking and Jim tells them about a sad story about a sailor who died on a small boat, not making it to shore to live. Jim tells them about how Celeste got taught to speak because the sailor wanted company because he was on the ship for more than 300 days. He then tells Violet and Shawn that he found the cat and kept her as his pet. And after the story finishes, Violet asks Uncle Jim about a locked door. In a deep voice he tells them never to open it.

Being kids, Shawn urged Violet to open the door and then Celeste comes. She sees them opening the chest and says she'll tell of them. Not worrying, they discover a chest full of old jack-in-the-boxes. Shawn is interested, so he begins turning them.

Eventually, they have done every one except one that looks like a pirate. Shawn, avoiding Violet's warning, spins it. They are covered in fog. Then the pirates in the jack-in-the-boxes grow big and become human size. One of the pirates revealed himself to be Captain Jack the Knife, and they see his scruffy crew of the two-headed Salt and Pepper McGee, Mad Madeleine, and another pirate. Shawn whispers to Violet that they need to find a way out, but the pirates are blocking the way, and they can't find a new way out.
