Welcome bro from the Swamp ...ive seen some crazy leaves at first them they seem to make better leaves as they grow ....I have a creamy dragon that gave me weird leaves on the first set then they came out all beautiful looking .....
I am not 100% sure but I think it happens when coming out a tough shell ...
I wouldn't worry about it unless they all come out looking like that ......then u can introduce yet as a mutant maybe lol
