Symbols in fire

I was playing IX and noticed these symbols in the temple fire trap thingies. I wonder what they are.

I think you have to kill certain zombies in a certain order in the spawn, and in the temple for an Easter egg step. The fire has the same symbols for the step in the Easter egg where you have to kill certain zombies in an order in the tower of Ra. I haven’t tried it yet, but it gives you 5 symbols when the fire is lit corresponding to the different zombie types.
