Quick correction- we call Orthus the father of Cerberus in the episode, but it's actually Typhon! Just swap 'father' for 'brother' and everything still works.

The final and most dangerous task is here, and we've got to go down into the underworld... We've got the whole package: Heracles solving fighting-based problems; Harry Potter connections from Cassie, and Vince going down a rabbit hole about mythological chronologies!

Back in episode 33, we examined what the ancient authors had to say about the phoenix. Well, this time the basilisk is under scrutiny! Also, find out which snake we think it probably sprung from! That and Part II of Harry Potter references...

Originally meant as a wedding gift for either Zeus or Hera, the Golden Apples lie in a garden far in some direction- either north or west, the sources disagree. Look forward to a cameo from a sly Atlas! He may have already become a mountain due to Perseus' shenanigans in episode 17 if you believe Ovid but hey, who's really keeping score... Plus sky giraffes. We can't forget about those.
