These could live alongside the chicken lizards, like we have dogs. The chicken lizards have these as pets.
I think they’d hop around like a edgy, be the size of a Rottweiler sitting down, have the ability to climb and swim at high speeds. But they can only digest fish food and worms. Humans wouldn’t keep them as pets because touching their slimy bodies and hand feeding piles of earthworms to them would repulse most people. Whereas the chicken lizards are more than happy to chew up worms and spit it into the fishy mouths.
