Know your monster: Scylla and Charybdis

Scylla and Charybdis are two bloody monsters (sisters I think). Scylla is a giant monster that lives on the top of a giant mountain (Scylla fact:only her mother can tame her) and Charybdis is a monster that lives in a BBBBBBBBBIIIIIIIIIIIIIIIIGGGGGGGGGG whirlpool and the people that see her get eaten alive in a few seconds later. Anyway, Odysseus is the ONLY guy known to have survived.
