My 6yo is super into me giving him the chills lately, but the only rhyme I can remember is the one that was more popular when I was older...which is rather gruesome.
FYI, the one I can remember goes:
Treasure Island, Treasure Island [slowly drawing a large circle each time you say it]
X marks the spot. X marks the spot. [making a large X each time you say it]
Dot, dash, dot, dash, question mark. [self-explanatory]
Spider crawling up your back--gotcha! [fingers crawl up back and grab the back of the person's neck]
Spider crawling up your back--gotcha! [same as above]
Dagger in the back--blood rushes down! [pound your fist between shoulder blades as if stabbing, then run your fingers down from there as a river of blood]
Dagger in the back--blood rushes down! [same as above]
Cool breeze, tight squeeze, now you've got the chills! [blow on the person's neck, squeeze both shoulders, and lightly tickle fingers all over back]
I've been skipping the "dagger in the back--blood rushes down" bit with him, but I'd love to remember the clean rhyme I learned when I was really little. I know it started out "dot, dot, dash...dot, dot, dash..." And I'm pretty sure you pretended to crack an egg and have the yolk run down. I've searched online and found nothing like it, just odd versions of the one above. Anyone?
