It’s obvious that this is a depiction of the aftermath of an ancient person consuming spicy food. That is flame shooting out of his butt and all his animals are scattering. The animal on the right didn’t escape and was caught up in the conflagration.
How do I say this politely? Umm... how about... Bzzzt! Wrong!!!
The picture is so obvious I can not comprehend how y’all can’t see it clear.
The item in the tall thing’s hand is, of course, high rise office buildings. Note the windows. The wobbly construction indicates the image pre-dates building codes.
The tall thing is tall, has short fore arms and a tail. Obviously its a proto Godzilla.
The worm thing is actually a giant carnivorous Mothra prior to its change to a moth.
The goats are simply place holders for the time when automobiles are invented as items to be stomp crushed by the Godzilla critter.
The man on fire is, of course, Man on Fire:

Man of Fire is waiting for whichever of the monsters wins the throw-down so’s he can take care of Last Monster Standing.
