High, Low, Medium, Slow

Thanks to Kathleen Garber, who helped me solve this skipping mystery. Here's the complete verse:

Turn the rope according to the words:

Hi, low, medium, slow,

Jolly ol' pepper and away we go!

Wherever the skipper gets mixed up in the ropes during the rhyme, that's how they need to skip the next time they're in. "High" - the skipping rope is a foot off the ground; "Low" - the skipper needs to bend down to skip; "Medium" - normal skipping; "Slow" - slow skipping; "Pepper" - really fast skipping.
