How did Psyche accomplish her tasks?

Task 1: Sort the Seeds

Some ants came by and offered to help Psyche sort the mixed seeds into individual piles.

Task 2: Get the Golden Fleece

A little green reed offered her the information she needed: wait until the sheep sleep or leave and collect it from the bushes near where they were grazing.

Task 3: Get the Water From the River Styx

An eagle carries a jug and brings her the water.

Task 4: Get the Beauty From Proserpine

A tower gives her directions in the Underworld and tells her to bring a penny for Charon, and a cake for Cerberus.
