Did you know that Vreka are addicted to the smell of vanilla? Although they can often control themselves, a stressed or angered Vreka will tear its way through anything in order to locate the source of a vanilla scent, and have been known to aggressively guard vanilla produce farms and factories.
The main reason for this aggression is because Vrekan younglings are born with a strong vanilla scent, and their tears produce an even stronger smell, forcing older Vreka to look after them.
