I grew up in Africa and there was a legendary beast called Bongolo which was a jet black centipede about 6 inches long who would always turn up in the playground when least expected. We would play for a while and then in a moment of distraction the bongololo would have disappeared although quite how would be a mystery as it always seemed to move very slowly but disappear very quickly. Later said Bongolo would turn up wherever we went and the modern myth is that it's in fact the same one. So I wrote this song to celebrate a bit of my childhood.

And whether great or whether small
my favourite animal of all
Has a thousand legs or maybe more
and goes bongololo when he's sure

First he looks this way and then he looks that
as if he was waiting to take off his hat
But hat he has not, nor tail, nor ears
and when long thin and black maybe no fears

When moving along he goes at great speed
one bong and a go, one lo and a bong
which is why we gave him a name to pay heed
to follow these moves takes animal creed

But there is one secret I have to tell
look away for a sec and all won't be well
For when you look back he's sure to be gone
and the theory of this is the rest of my song

for when you are watching my little black friend
his legs go very fast but his body's no end
and when you are not his legs go very slow
but his body goes BONG as a rocket might go.

there's another verse but my finger is tired. I don't have a tune for it - any suggestions?
