I believe in a number of things
Horses, gators, even mammals with wings
I believe that a bird and a rat, got cozy one night
and that became that
that as in bat
a bat became that
from the bed of a bird and a rat.
the bird saw the rat being chased by the cat
that they had in common, the cat was a brat
So they chatted and chatted, till the chat became flat
I haven't a bed, but I do have this mat, said the rat.
This mat will do, the bird said as she sat.
soon that became that
that as in a bat
a bat became that
from the bed of a bird and a rat.
