The Flea by David L Harrison
(Ralph in pre-swallow mode)
(the animals Ralph decides to ingest.)
A flea known as Ralph swallowed a cow
It's a mystery how.
And after the cow he swallowed a horse,
a huge one of course.
But with the giraffe he ran out of luck
It's legs got stuck.
It's impossible now to understand Ralph
wif giraffe in hif mouf.
(Ralph giving the giraffe a go, it doesn't end well. I had a manila folder attached to the back of the construction paper which held the cow, horse, and giraffe upper half. You can kinda' see the slit in the first image. There was also a little slit at the bottom [behind the body of ralph] which allowed for the raising and lowering of his great maw [which had a t-cross at the bottom so it wouldn't slip out].)
