Synopsis
In Zack's Lair, Agent Yellow and Bart meet with Zack to go over their future plans when they get a visit from Pig King. Pig King tells them he has a plan, but he needs their help. Agent Yellow tries to kick Pig King out of the Lair, saying he's not on the schedule, but Pig King ignores him. Pig King tells him that the shard Zack is seeking could be hidden on Fin-Land and even if it's not, he could use Fin-Land's resources to make the search easier instead of hiding in the shadows. Zack says that he can't be seen leading an invasion of his own home world, so he will allow Pig King to lead the invasion with the help of Agent Yellow, Bart, and Dr. Robotnik, but Zack warns that he will have his eye on Pig King. As Pig King leaves, Zack says he will have to take care of Ted.

At TFAWPS Tower, Pink Panther, Paco, Mofo, Buster, and Wally play a game of basket dodge ball, while Ted, Oscar, and Phoebe watch from the bench. Buster and Wally get into an argument over being a ball hog, but the fight is broken up by Mofo. Suddenly the team gets a call from Sonic, who is out on a recon mission. Sonic says that there has been a decrease of activity near Zack's Lair and Pig King's Castle, which concerns him, but Oscar initially shrugs this off as a good sign. Sonic says that with nobody at Zack's Lair, no one will be there to guard the shards and now is a perfect time to send a team in to steal it back.

Ted, Pink Panther, Paco, Mofo, Buster, Oscar, Phoebe, and Wally meet Sonic on the outskirts of Zack's Lair. Sonic tells them that there is a force field surrounding the Lair and that they are going to test out some new technology Lupina whipped up for them. Unbeknownst to them, Zack watches from inside his room on Fin-Land. Sonic fires up a new battering ram saying that this machine will be able to break down these walls faster than Paco could. Paco bets Sonic that he's be able to break it down faster. Pink Panther tells them that instead of talking about doing damage, they should actually do some and they all start attacking the force field together. Suddenly, a laser activates firing at them, but Ted takes it out with ease. Suddenly, a portal opens and Wave steps out, greeting Ted. Wave tells them that strange characters have arrived in Fin-Land and that King Salamence requests Ted's presence. Ted realizes that this must be important and brings Pink Panther, Mofo, Buster, and Wally with him. Wally and Buster continue their argument with Wally saying that Ted picked him first, but Buster says that they need full-time team members only, but Pink Panther stops them and the group departs for Fin-Land.

Ted, Wave, Pink Panther, Mofo, Buster, and Wally arrive at the Cosmic Tunnel, the gateway connecting Fin-Land to the Land of Ooo. As they marvel at its beauty, Wally questions how its possible to walk in the tunnel, but Ted says they don't walk, they ride. Wally teases Buster about being too scared to enter the tunnel and they two jump in, followed by everyone else. Arriving on Fin-Land, they witness the Fin-Land Army battling with a group of robots, led by Agent Yellow, Bart, Dr. Robotnik, and Master Robot. Pink Panther realizes that Zack and Pig King must be working together, but can't figure out why Zack would invade his home world. The group runs into battle, taking out many robots. Pink Panther takes out a few and notices Pig King leading the army and the two begin a fight. Zack watches the battle unfold in the distance. Wally battles Dr. Robotnik, Mofo battles Bart, and Buster battles Agent Yellow. Wave greet Vector, Charmy Bee, and Espio, also known as Team Chaotix, and they begin an attempt to take down Master Robot.

Back on the Land of Ooo, Sonic tries out more equipment on Zack's Lair to break through. After the device doesn't work, Paco makes another futile attempt. As the battering ram and Paco continue their assault, Phoebe points out an energy surge building up in the force field. Realizing what's about to happen, Sonic warns Paco to stop attacking the force field, but it's too late. Paco strikes the force field and is immediately electrocuted. The battering ram explodes. Oscar and Phoebe rush ahead to investigate the explosion while Sonic goes to check on Paco, who assures him that he's okay.

Back on Fin-Land, Zack watches his robots lose the battle. Zack orders Pig King to work harder and stop slacking off. Master Robot picks up Vector and throws him into a wall, injuring him. Angrily, Ted heads into the castle to investigate, realizing Zack was behind the invasion.

Ted flies into Zack's room and tells him to call off the invasion, on orders of the King, but Zack refuses. Zack tells Ted that King Salamence has no idea what Zack's been up to and he'd like to keep it that way. Ted retorts saying that King Salamence asked him to stop the invasion and that's what he's going to do and the two begin a fight. As the two fight, Ted questions Zack on how he could betray his people and that as the prince he should have a lot more care for the the Fin-Landians who are getting hurt. Zack says that ever since Ted arrived on Fin-Land, his father has always cared for him more and says that King Salamence would rather of Ted the prince than himself. Ted replies that it is untrue. Zack says that if he could collect the shards, he would show his father that he is just as good if not better than Ted.

As they continue to fight, Ted's energy blasts enter the battlefield, knocking out Dr. Robotnik, prompting Wally to tease Buster, saying that he's already stopped his bad guy. Buster says that Wally has stooped so low that he's taking credit for Ted's attacks. Mofo tries to get them to separate, but this causes him to be hit by a laser fired by Agent Yellow, knocking him down. Buster and Wally rush to his aid, taking down Bart and Agent Yellow along the way. Meanwhile, Pink Panther battles Pig King. Pig King says that by tricking Zack into invading his own planet, it would allow Pig King to step in and become the new king of Fin-Land. Pink Panther calls that a terrible plan and that Pink Panther will send Pig King back down to his sad castle back home. As they fight, Wave steps in and the two team up against Pig King. Buster and Wally bury the hatchet.

Ted pushes Zack towards the window in his room. Looking out, Zack realizes that his invasion is being pushed back and escapes out the window, meeting Buster, Mofo, and Wally. The three try to apprehend him, but he quickly escapes. Ted meets back up with them, having just come from the vault, and realizes that Zack has stolen the shard they have hidden there. Ted says that as long as Sonic is able to get the other shard out of Zack's Lair, then they should be safe. Ted apologizes for abandoning the team during combat, but they forgive him.

Losing the fight with Pink Panther and Wave, Pig King calls Master Robot in for assistance. Vector, Charmy, and Espio follow him and join the fight. After a prolonged battle, Pig King manages to subdue Pink Panther and Team Chaotix. Wave attempts to make a strike against Pig King, breaking his crown, and is stopped by Master Robot. Wave tells him that he'll never be the king of Fin-Land and that she's sooner die than live under his rule. Angered, Pig King orders Master Robot to get rid of Wave and he throws her off of Fin-Land, sending her into a black hole. Suddenly, Ted arrives, witnessing what happened and blasts Pig King and Master Robot with an energy blast, knocking them both out for good. Ted, along with Team Chaotix, look out into the void, realizing they've seemingly lost Wave forever. King Salamence and Queen Lucy arrive and take Pig King and Master Robot to the Fin-Land Dungeon.

Zack arrives back on the Land of Ooo and returns to his Lair, realizing Sonic, Paco, Oscar, and Phoebe have located his shard and stolen it, much to Zack's anger and dismay.
