The Spoonbill Generator

This Plasticene®'s Jurassic, don't you know?       [Apsley ]

And yet it will not serve to mould my hat       [Bex ]

Or imitate dark crystals in the snow       [Apsley ]

Nor any other trick to rival that       [Roland ]

Despite of this, such stuff is ages old       [Apsley ]

And more than fit to face the future bold       [Roland ]
