In this episode, Sonic and the others find a meteor in space while searching for the Chaos Emeralds. Tails pulls it in, and they find it to actually be a space ship. Inside, small chao-like creatures called Marmolians are discovered and it is revealed that they have the Green/Cyan Chaos Emerald. The Marmolians and Sonic go back to their home planet, the Planet Marmolim, and Sonic destroys a diseased part of the planet that encased the Planet Egg. Amy thinks they have magic on the planet, so she tries to put a love spell on Sonic. However, it ends up backfiring, and instead works on Tails and Cosmo at the end of the episode, leading to the two embracing while watching the moon. This episode basically confirms Tails and Cosmo's relationship, while Amy gets extremely angry that she didn't catch Sonic.
