No yb there, but a nice normal.
The name itself is often misleading to new yb or yb-lookin ball python keepers. Yb doesnt literally mean they have yellow bellies. Their main characteristic is the rail track-like markings running both side of the belly, high flames and sometimes a distinct head marking. You can check alot of pictures here to make as your reference. Try checking Albey's and the Hunter's Guide. Hope this helps
