you're welcome:

here's another one you could learn if you wanted to- the butterfly one

start off with your finger on somebody's arm slowly moving your finger up while singing:

the creepy crawly Caterpillar, crreep creep creep

the creepy crawly Caterpillar, goes to sleep (stop moving your finger)

Caterpillar, by and by

turns in to, a butterfly (on the word butterfly tickle the other person down the arm like a really fast butterfly)
