Good Intentions.

The relatively primitive state of paleontology during the attempted piecing together of the earliest procured IIguanodon skeletons, rendered unrecent life sized representations, frrozen in their imaginary roaming of Crystal Palace Park, reminiscent for Rodney, as he called himself on Earth, of his pet Wookawaka back on Wikawooker, which h he'd cured of being turned to stone with a device his vet gave him.

Could it be used to 'Cure' these ones of merely being life sized models?

It could!

Unfortunately either Rodney or the machine didn't know Iguanodons are supposed to be vegetarian so they ate everyone in the park.
