The term 'labyrinthodont' is no longer used today. It was a catch-all term for temnospondyls and similar 'amphibians' with conical, infolded teeth. So with that in mind, there is no basic animal I can really compare this to, so I'll go with Eryops, which is known from fossils in Europe. These models are made to look like toads, complete with bumpy skin and a tympanum. Eryops itself looks very different from a typical toad, and acted different too. It was a large, mostly terrestrial, scaly animal that patrolled the Permian ecosystem. The tail would've been much longer. The body would've been less arched and more streamlined in form. The head, while pretty big, was flattened with eyes facing upwards in the skull.
