I'm being swallowed by a boa constrictor, [Repeat twice]
And I don't like it one little bit!
Oh no! He swallowed my toe.
Oh gee! He's up to my knee.
Oh my! He's up to my thigh.
Oh fiddle! He's up to my middle.
Oh heck! He's up to my neck.
Oh dread! He's up to my . . .
[Make sound of victim being swallowed up.]
