More Words, Deeper Hole

Orpheus shows up late, by which time Eurydice is almost out of Hades and is quite bitter about the whole thing. He finds himself stuck in her place, and she has to go back for him. Only by working together can they both escape. Add a cute animal sidekick and you've got a Disney movie. Hmm, make it a squirrel, say, and represent Hades-the-ruler-of-the-Underworld with the "traditional" cloaked skeleton with a scythe, and give Hades a "Death of Rats" sidekick who gradually comes to the realization that Orpheus and Eurydice should be let go, and in turn helps to persuade Hades, and then there can be the tragic romance between the two rodents. Yeah, that would work.
