The show opens with a sequence inside Cosmo's ship and ends when Scarship (see previous episode) destroys it, leaving Cosmo alone. Then, we find out the Blue Typhoon's crew on a new planet. It seems that there's a Chaos Emerald nearby. Tails, Knuckles and Cosmo follow the emerald's track to an abandoned city. Knuckles discovers a deep gorge. Lower, there's a cave. Tails and Cosmo enter, but Cosmo accidentally pushes a button which launches an avalanche and seals them inside the cave. Tails still receives the emerald's signal and he and Cosmo pursue their searches. Inside the Blue Typhoon, Amy receives a distress call from Knuckles and she informs Chris, Sonic, Cream and Cheese (who are all aboard the X-Tornado) of the situation. Inside the cave, Tails and Cosmo discover a big factory full of Metarex. They enter unnoticed and they find the Chaos Emerald inside a manufacturing plant of fake emeralds. They are found out by the Metarex, but they are able to escape with the White Chaos Emerald. Then, Tails fools the Metarex with special "fireflies". Tails and Cosmo are found retrieved by the Metarex and they steal the emerald from them. Tails engages a fight and Cosmo can take back the emerald. Tails is caught by a Metarex, but fortunelately for them, Sonic and the others come to the rescue. Tails and Cosmo also are starting to have feelings for each other.
