A special form is breeding only variation of the base marking. These markings follow the rules of their original gene but with differences in how they display.
They will be found in the guides for their respective genes.
A croc must have a carrier of the form in their visible linage for them to inherit it. Please be aware these are not rolled during breeding and will not appear in eggs. You will need to be aware of your croc's linage.
Emperor Zelos has a special form of Python, "RPB Python". If any croc related to him gets the gene Python they can inherit the special form of python. If the croc does not have python in their genotype then they cannot inherit the special form but can still pass it on as long as a croc in the linage carries the special form. If there is no croc in the lineage with the special form it is no longer passable in the linage.
