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.
