Pink hippos on the shores of Lake Victoria

I swear I saw two large Pink hippos on the shores of Lake Victoria.
They crossed the road and got into the city-
It was Saturday night after all.

Perhaps they were going out to tea.
Or to the disco I cannot tell,
But I could tell they were in a hurry.
And as we braked and sighed and were totally flummoxed
They went their way.

But now I am not  so sure if they were hippos Or pink elephants coz
They were were
Quite big.

Could they have been flamingoes
Walking in hippo formation?

If flamingoes do go out at night.

Perhaps they do
When the circus is in town
And when the Flamenco dancers put on a show.
