The great thing about this activity during a Pirate party is not only that this type of party can be crazy. But there are some great Pirate books out there that can be read. You can even have the kids participate by repeating the words that the crew does.
My favorites are: How I Became A Pirate and Pirates Don’t Change Diapers. I think you would be hard pressed to not find this author. And if I’m not mistaken, I think there is another coming out. These stories are very fun and a great activity for a Pirate Party!
