My Name Is Jake, Part 2 (Originally Aired 9/11/1998) -- Still trying to get over the fact they just met an alien, the kids decide to practice out their morphing powers, learning new rules as they go along. Cassie had already morphed a Horse, Rachel tried the Cat while Marco used the Rat as a morph while Tobias (who acquired the red-tailed hawk) runs away. It also seems like the Yeerks are heavily interested in cleaning up the area. When the Animorphs found out Tobias was missing, they decided they would get the disk back before Tobias does. When they arrived construction site, they found the disk but to get it, Marco tricked the Controllers that there was a ship landing, and Cassie morphed a horse with blue paint to pretend to be an Andalite while Jake as a Dog and Rachel as a Cat sneaked over to grab the disk but was captured by Chapman. Tobias came to the rescue and they all escaped.


The Underground (Originally Aired 9/18/1998) -- The Animorphs tried out the disk but nothing happened. Jake and Marco realized that someone very close to Jake is a Controller - his brother, Tom. Jake wants his brother back, and he'll do anything to do it.They tried out ferocious animals from the clinic that Cassie's Mom works in (Jake acquired a Tiger, and Rachel acquired a Lion), and the used it to try and free all the humans in the Yeerk Pool which is located under the school. They escaped with no free humans, without Tom, Tobias was gone (Could have been captured by the Yeerks), and they lost the disk.


On The Run (Originally Aired 9/25/1998) --  Tobias is still missing, and so is the Andalite disk which Jake lost. Jake and Marco get an on-line message in Cyberia from the Yeerks offering them a trade, an Andalite for the disk. They planned to trick the Yeerks by giving an animal to the Controller which is not really Andalite but the Yeerks will assume that is in morph, while Jake morphed to a Lizard to use thought-speak. When Marco was caught shoplifting Jake, he had to morph a rat to escape. Rachel and Cassie goes to a Sharing meeting with Melissa and Rachel morphed a fly to find out The Sharing's future plans that coming up. Jake and Marco got the disk after having gotten out of a city garbage dump where Jake had to rescue Marco from as a Dog, but the disk was fake, it was tracker to find them, so it was up to them to trick the Yeerks trying to look for them.


Between Friends (Originally Aired 10/2/1998) -- Tobias is back but he is stuck in Hawk form because he stayed in morph for over 2 hours. Rachel is worried about Melissa, because her father is a highly-ranked Controller, so Rachel morphs Melissa's cat and enters the Chapman household to rescue Melissa from being a controller. Unfortunately, Rachel gets captured by Chapman and was taken to Visser Three. Jake was spying and morphed a dog to go save Rachel. They escaped when Chapman was trying to protect the host's daughter, Melissa from becoming a Yeerk. Jake and Rachel were able to escape.

The Message (Originally Aired 10/9/1998) -- Cassie and Tobias thinks there is another Andalite on Earth because they heard noises from a distance, they went into convulsions, they heard some strange thought-speak message. It sounds like something has crash landed and needs help. Rachel was at her father's so the Animorphs checked it out and found out there was another Andalite on Earth. Visser Three had been contacted by the Andallite too, it's a race to find the source. If the Yeerks find the messenger first, the Andalite will become a Controller. So Cassie, Marco, and Jake set out on a mission to find the creature. They end up discovering something they never thought they would, a new friend. But at first, the Andalite named Aximili-Esgarrouth-Isthill did not believe they were allies of the Andalites because they were not their species, and followed Visser Three. Cassie morphed a skunk and saved Ax, and the three kids and the Andalite escaped by morphing butterflies. Ax and the Animorphs talked about Elfangor, and other things when Ax acquired all the Animorphs (except Tobias) DNA Pattern and made a new person.

So the Animorphs have a new weapon, but how are they supposed to use it? They can't use it on the Controllers, that'd be like hurting the slaves to spite the slave owners. At the restaurant, the Animorphs try to enter the Yeerk pool but it did not work because a Gleets BioFilter was there to destroy all lifeforms without Yeerks in their brains, but luckily, they escaped as roaches.They have to go directly to the source, dig underground as ferrets. When they reached the Yeerk Pool, they threw Oatmeal into the Yeerk Pool, and Tobias was hurt by a weapon used by a Hork-Bajir.

They brought him over to Marco's house, where he went crazy over the spicy food that Marco's father made him eat. Ax then breaks into a satellite company, and modifies the computers so he can phone home. Jake and Marco also sneaks in by morphing lizards. When he does, his father picks up and Ax places the dishonor of giving a lower species Andalite technology on Elfangor, he takes on the burden himself, disoberying the law of Seerow's Kindness. But that's not all. Turns out that the Yeerks are hot on his trail. And now Ax wants to take revenge on Visser Three and began to fight Visser Three.
