From time to time we will find a peculiar abberation on a babs horns, a handful of sharp bits resembling thorns growing from an otherwise normal set of horns. Babs with thorned horns tend to have a rough time with the normal ways of expressing affection as the barbs on their horns bring pain to those they tap against.
A babs horns grow up to a certain height naturally, stopping their growth and staying healthy and dense. There have been anomalies recorded of babs whose horns don't know to stop growing, allowing for odd plates to form at the base, as through the horns are trying to regrow from step one. The plates give the horns a strange blossoming appearance.
