the telltale signs can be subtle given the variation within the morph but some other things to look for include the marking on the head and flames - blushing that comes up from the belly between the pattern.
the pattern looks like a clash of BEL and an enhancer gene, there's a good mix of alien heads, cheerio's/speech bubbles and attempted cheerio's/speech bubbles. your Spark (combo) theory is a good one.
regardless - u definitely have a morph. it's just unknown which enhancer and BEL gene is all in there IMO until it's proven out.
Edit: pair it to a YB or Mojo and see if a Puma or Passion/Potion or BEL animals hatches.![]()
