The anichinnus is a most minute marsupial

So tiny, it is knee high to a mouse,

But it’s a most voracious beast

And when it wants to feast

It will do it’s best to infiltrate your house.

The female of the species has a hard life,

She can produce twelve offspring in one go;

And in the breeding season

It only stands to reason

If one or two went missing, she’d not know.

Now you may think the male has it easy-

For all he has to do is propagate,

And he occupies all hours

Not just hiding in some flowers

But taking every opportunity to mate.

But fate has quite a nasty trick to play

On the males of the species anichinnus,

For, when the mating season’s done

They are wiped out, every one;

In every situation there’s a plus and there’s a minus.
