I think it's kinda like rock paper scissors here man... Swan flaps wings...buffets unicorn....honks ...pecks unicorn... (sounds harmless and cute...but geese and swans peck REAAALLLYY hard man...we used to have them on the farm ...some people have them as guard animals...that is how much it hurts..It really really really hurts) Unicorn stamps feet..snorts...tramples swan...spears swan....swankibob. Unicorn beats swan. Not a pretty fight Not a pretty sight. feathers and blood everywhere.
