Their History: Yitzchak, and Yaakov, are brother's... Their parents, sold them for more money. Their owners worked them so hard, that the younger Yitzchak died, Yaakov didn't want to be left alone with their new owners, so he killed himself too for freedom. Yitzchak was so sad and lost to be alone without his brother, but when Yaakov came... Yitzchak became so happy, the smile would never go away... Heaven and The Underworld didn't want to accept them. So instead... They were banished to Earth never to leave it... Yaakov was so angry, his frown never went away... So while they are there, They might as well keep the ghosts on planet Earth hidden, And NOT be discovered by Dib!

I know...I'm losing it with all these characters but...I'm writing a story about them! ...They have no feet!
