A Pizza the Size of the Sun

"I'm Miss Misinformation, it's my gratifying task
to tell you all you need to know; you only need to ask.
The seas are thick with elephants, the skies are purple straw,
you measure with an octopus, you hammer with a saw.

"Rat for lunch! Rat for lunch!
Yum! Delicious! Munch munch munch!
One by one or by the bunch!
Rat, oh rat, oh rat for lunch!"
