I've made summaries for all four of these.
"3 Transformers",
Episode 1, "Let's Make a House!"
in the year 20XX, three Transformers (Optimus Prime, Ratchet, and Bumblebee) come to a new land to live there, and each decide to build a house for them all to live in.
Bumblebee decides to build a house made of straw because it is light and easy to work with, completing his work in less than a day. Optimus, however, is worried that the straw house may not be able to withstand an attack should one occur, and Ratchet thus decides to build a more durable house. Bumblebee, however, does not take their concerns to heart, basically telling them both not to worry so much.
Nonetheless, Ratchet proceeds to build a stronger house out of wood and made with more care, which takes him two days to complete. Optimus is more impressed with this house, but still can't shake his anxiety.
So, Optimus takes it upon himself to build an even stronger house, this time one made with bricks. Unlike the others, it takes Optimus a whole five days to complete the brick house. And it turns out to be a good thing that he finished when he did, too, because, all of a sudden, the ground begins to shake.
"The footsteps of a sinister sound echoed in the distance."
To be continued...
"3 Transformers", Episode 2, "Invasion! Death Metal Empire"
Yesterday, the three Transformers (Ratchet, Optimus Prime, and Bumblebee) built their respective houses in the land that they had come to and in which they decided to live. But, there was a certain fear about it...
Now, animals have gathered in the land where the three Transformers have decided to live, and peace continued for days. Until one day, when the ground shook and scared the animals away. The three Transformers each fled into their respective houses for safety. Two members of the Death Metal Empire, Death Rex and Gilraptor, arrive in the land with the intent of taking it for themselves.
The two first approach Bumblebee's house. The two demand Bumblebee to open the door, but he refuses and provokes them into attacking his house. Gilraptor responds in kind with his special move, Display Star, which he uses to slice and tear Bumblebee's house to shreds.
Bumblebee manages to escape to Ratchet's house, who lets him inside and shuts the door as Death Rex and Gilraptor make their approach...
"3 Transformers", Episode 3, "Wooden House"
The three Transformers had built houses for themselves to live in, but the straw house Bumblebee had built was attacked by the Death Metal Empire. Bumblebee fled from his destroyed home to that of Ratchet, which was built of stronger wood.
The Death Metal Empire approach Ratchet's wooden house and demand they be let in. Ratchet refuses and dares them into attacking his house. Angered, Gilraptor powers up and strikes the house, but is knocked back when he finds the house to be much more durable than expected.
Ratchet and Bumblebee are relieved, but Death Rex steps up to take care of this himself. He powers up his special move, "Death Blast", and rams his weapon into the house's wall, collapsing the structure upon impact. Ratchet and Bumblebee fall to the ground and make haste for Optimus Prime's brick house.
Optimus lets the two inside and shuts the door behind them. Frightened, Bumblebee and Ratchet alert Optimus of how the Death Metal Empire has destroyed both of their houses. Optimus says he has an idea, while Death Rex and Gilraptor make their approach...
The final decisive battle will soon commence!
"3 Transformers", Last Episode, "Final Battle! The Strongest Fort"
The three Transformers have had their straw house and wooden house both destroyed by the Death Metal Empire, and now the final battle will commence at the brick house.
Death Rex and Gilraptor arrive at the brick house and threaten to destroy it if its occupants don't let them in. Optimus, however, is not afraid and insists that his house is too strong for them to destroy.
Angered, Death Rex orders Gilraptor to attack the house with him together in unison. They both power up their respective attacks, "Death Blast" and "Display Star", but when the two strike the house, they are knocked back by its resilience.
The two refuse to give up and Optimus goads them into attacking some more, but the brick house will not break. Finally, the two Death Metal Empire members fall over in exhaustion. Optimus sees this as their chance, but Ratchet and Bumblebee are confused as to why Optimus is not afraid.
When Optimus runs outside, he is stopped when he sees that the animals of the land have returned. He is also surprised to see the animals joined by members of groups called Freedom and Supreme.
Death Rex and Gilraptor get up and also spot the members of Freedom and Supreme. Wanting nothing to do with either of those groups, the two turn tail and leave. Bumblebee and Ratchet rejoice in the Death Metal Empire's retreat.
Bumblebee commends Optimus on his brick house, and Optimus thanks Freedom and Supreme for coming to their aid. The groups then all mingle together in cooperative peace.
