as stubborn as
a mule
as gentle as
a lamb
as healthy as
a horse
as blind as
a bat
as clumsy as
an elephant
as sly as
a fox
as graceful as
a swan
as curious as
a cat
as hungry as
a wolf
as proud as
a peacock
as quiet as
a mouse
as poor as
a church mouse
as strong as
an ox
as busy as
a bee
as brave as
a lion
as wise as
an owl
as free as
a bird
