"Bylo to zvíře se čtyřma očima."

Translation: It was an animal with four eyes.

[ChristophS49077]

I am always like "What?" until I realize it's not the reflexive "se".

[federicourban]

Why one of the translations is "this was an animalwith four eyes"? Shouldn't it be either "that was" or "there was" ?

[Hatch-Slack]

Because "to" does not belong to "zvíře" here. "Bylo to/Je to" is an expression which means "It was/It is".
