Hide-and-Hippo

You can't hide a hippo in a custard pie
You can't hide a hippo in a cloudless sky
You can't hide a hippo in pot of glue
You can't hide a hippo in a training shoe
You can't hide a hippo in a garden hedge
You can't hide a hippo on a window ledge

You can't hide a hippo if you paint it green
You can't hide a hippo on a submarine
You can't hide a hippo in a pile of peas
You can't hide a hippo on a high trapeze
'Cause hippos are huge not skinny and sleek
So totally rubbish at hide-and-seek
