Can you talk like Captain Sillyvoice?

Here is a sample page from my new book - Captain Sillyvoice and his Pirate Band . 

See if your children can follow the instructions and speak with a squeak like the Captain. Of course, any adults wishing to give it a go too should not feel silly about doing so, not at all, not in the slightest. Well perhaps a little, but I say go for it anyway!

With my daughter, the result is normally some squeakiness but mostly a lot of giggling. 

Please post to let me know how if you've tried it and whether it worked!  I'd love to hear from you.
The book is available on Amazon in Paperback and for Kindle. Here are some more sample pages:
