Hybrids are the offspring that come to exist when two subspecies of beblunes breed with each other with a heart quartz present and have a pup! Each unique pair of subspecies creates a new hybrid! Check out the chart below to see what combinations make what kind of hybrids!
Without the presence of a heart quartz, a breeding between 2 subspecies will have a 50/50 chance of the pups being either subspecies of their parents! This also applies to breeding a non-hybrid with a hybrid, such as creating mowl pups from breeding a mowl and a coalgur together!
