Just my opinion, but after much q&a with breeders and other members, she's def not a fatty Bp's should be a round body, not pointed towards the top or triangular. personally, if I was looking to buy a snake and it was only 120g at 6 months old, I would pass, and fast. She is a very good grower, but the very lightest I would want / think was healthy, would be a 300g at 6-7 months. I'm not saying your snake is unhealthy, but to me it seems like if it is infact round bodied, it's a very slow grower, which is fine too.

She is most definitely not fat. She's pleasantly plump, and my best grower

My mojo,about the same age, is only 450g (he's about 6 months).
