## Plot

This episode starts with Gamma and Daisy landing on Bondi Beach in Australia, which Daisy notes strongly resembles Downunda from Mobius. Gamma has picked up the location of his next target - E-119 Upsilon. They decide to go into an area more isolated from humans, so as not to draw attention.

Suddenly, Gamma is struck down by a Bomberang and a wallaby - Walt - is forcing Gamma down. Another Mobian, this one a koala named Barby, tackles Gamma and manages to free Daisy. Much to the duo’s shock, Daisy is fluttering around in a fantic state. Walt and Barby decide to take Daisy to see Guru to see what is going on.

Walt and Barby come across Guru - who’s an emu, and two other Mobians - Stu, a wombat, and Bill, a platypus - and Guru asks for Walt and Barby to bring Daisy closer. After more frantic chirping, Guru translates to his fellow Freedom Fighters that Daisy is powering Gamma of her own free will so they can free the other Mobinis. They’ve succeeded with taking down E-101, E-103 and all the E-100s up to E-118 thus far. Stu comments that he’s surprised that the E-100s have a choice like that at all and they mindlessly worked for Eggman, but, Daisy explains through Guru’s translation that submission circuits force them to be loyal to Eggman. Gamma had a Conscience Circuit to get him to differentiate right from wrong. Realizing their mistake, the Downunda Freedom Fighters bring Daisy back to Gamma.

Gamma’s systems boot back online and the quintet apologise to Gamma for their mistake. He accepts the apology, saying that his brothers have a less than favorable reputation and explains to them that Upsilon is nearby. Walt offers his and his Freedom Fighters assistance in combat, but, Gamma tells them that they are more fragile than him. Guru feels it’s not right to offer direct combat assistance to Gamma in this scenario, but, the robot still appreciates the help. They also admit they don’t know where Upsilon is or what he looks like. Gamma showcases the robot in question, which seems to somewhat resemble a grey and white version of Fully Charged Air Man. Bill realizes he saw the robot flying around last week and it was near Uluru, a famous rock formation named by the aboriginals.

Uluru doesn’t appear to have a Downunda counterpart, but, the group do see Upsilon flying around the rock and Gamma notes he can use gale-force winds with his cannons. Gamma also tells the Downunda Freedom Fighters that most of if not all of his brothers had fought with force instead of smarts, which is how he was able to bring them down. They decide that taking down Upsilon's turbine with a Bomberang would be a good idea and after it’s noted that Walt has plenty in his pouch, Gamma is surprised as usually it’s female kangaroos and wallabies who have pouches. Walt doesn’t want to talk about it and proceeds to successfully knock out a turbine with a Bomberang. Stu is surprised to hear the robot react with pain, but, Gamma explains that Eggman’s robots are built with nerve sensors. At this, Chaos Gamma goes up to attack Upsilon directly, but, he calls out Phi Troopers and Guard Robos. Seeing how Gamma would be outnumbered on his own, the Downunda Freedom Fighters leap into battle against the Troopers and Robos - save for Guru who isn’t much of a fighter. An angered Upsilon uses his Upsilon Tornado against Gamma, who switches to Guard Mode. While he is able to withstand the blast, some of the Troopers and Robos aren’t so lucky. Barby claws a few of the robots and tells Walt to get back to work on his lot after he gives her a compliment.

Gamma uses a Devastator on Upsilon which charges up an energized projectile. It fires at the evil robot, knocking him down to his knee joints. In a last ditch effort to win, Upsilon tries to use Upsilon Vortex to suck everything into a vacuum, but, it’s already too late and he sucks in a mine by mistake. Gamma reprograms him and a Mobini Koala is released, squeaking gratefully before scurrying away.

By now, Gamma finally gets properly introduced to Walt, Barby, Stu, Guru, and Bill, who’s real name is Duck. Unfortunately, Gamma had to get going, but, not before Guru realizes that if all the E-100s were to be destroyed, Gamma would have to be as well. Stu admitted that in order for everyone to be free, Daisy would have to be the last one to be freed, not any earlier than that, but, Gamma replies he’s already accepted their apology. Gamma flies off as the group wave goodbye to wish Gamma and Daisy luck.

At the Mobini Ranch, Amy is hoping to get Cream and Vanilla to bring in the Chao later, when the koala shows up. Amy identifies the koala as a boy. Manic tells the koala to play with the other Mobinis and Amy notes that the koala can teach Chao to play the trumpet, blow kisses, and wear hats. Manic wonders how that’s possible and Amy notes she’s an amateur Mobizoologist. Amy is upset as she knows that there’s only three Mobinis left to save before Daisy is freed and Brian and Lily longingly chirp for their sister as the episode ends.
