AXEL MYTHIC

OK HERE IS AXEL PICTURED AS THE GREEK SPHINX
THIS PICTURE COME OUT OF A TALK I HAD WITH
SHE HAS DRAWN AXEL AS A HARPY AND AS THE BIG GEEK I AM I COULDN'T HELP MYSELF AND POINT OUT TO HER THAT HARPIES ARE A SPECIE WITHOUT MALES SO TECHNACALLY AXELCOULDN'T EXIST.
SO I TOLD HER OF MY FAVORITE AND DESIDED TO DRAW HIM FOR HER SO HERE HE IS
HOPE U LIKE HIM!
NORMALLY HE WOULD ASK U A RIDDLE
THE MOST CLASSIC IS: WHAT ANIMAL WALKS ON 4 LEGS IN THE MORNING BY 2 AT THE NOON AND BY 3 IN THE EVENING.
ANOTHER IS: IM A QUEEN OF THE OCEAN BUT MY CASTLE HOLDS ONLY 2 WALLS
MY GOUNT IS AS DESIRED AS EBONY BUT MY HEART IS OF SAND
MY FARTER I DO NOT KNOW BUT MY MOTHER HOLD ME DEAR TO HER DEATH
WHAT AM I?
CAN U OR ANYBODY TELL THE ANSWERS? I KNOW BOTH ANSWERS
BUT FOR U TWILIGHT I ONLY THINK AXEL HAS 1 QUESTION: WOULD U PLZ COME AND PET ME
