They can’t find it, despite the coordinates on the map, Gus freaks out and begs Protoboy to come find them before they die of thirst and starts begging for a drink until he ends up licking a cactus and screams in pain, the cactus is revealed to be Moshimo in a costume and he says that their coordinates were correct, then the ground opens up and they fall onto a mine cart heading to the lab. Moshimo says that no weapon can stop Protoboy, Tommy then suggests turning up the output of Robotboy's particle beam to fry Protoboy's motherboard, Moshimo finds this a good idea and says that they will get started right away, the cart then flies into the lab. In the lab Moshimo, Miumiu and Tommy are fixing Robotboy while Gus watches the TV, which is interrupted by the news where it says that a cruise is in grave danger by Protoboy, which makes Tommy worried because his parents are on that cruise so he brings Robotboy with him to save them and the whole cruise. Gus initially stays behind, Moshimo and Miumiu don't appreciate this, so Gus goes and follows Tommy and Robotboy
At the cruise everyone is terrified by the disaster caused by Protoboy, except Tommy's parents who are completly oblivious of the situation. During this, Donnie is found by the fisherman, who happily gives him the choice between working or swimming. Robotboy, Tommy and Gus arrive to save the ship and stop Protoboy. While Robotboy and Protoboy face each other. Robotboy tries as much as he can to make his brother change his ways, but Protoboy does not want to. Robotboy flies away and hides to get Protoboy away from the ship. Protoboy loses Robotboy, but he gets an idea on how to get Robotboy to come out. To do this he dives in to the water, and flies into the cruise ship from underneath, making a big hole in the ship and grabs Tommy and flies off with him.
The gap in the ship is letting water in, and the ship starts to sink, causing more panic over the passengers. Gus abandons the ship by jumping in the sea. He swims away but is stopped by a shark. He tries to play possum, but it doesn't work and the shark eats him.
Meanwhile Robotboy is looking in the sky for Protoboy who has Tommy. He finds them and sees that Protoboy is seemingly slowly choking Tommy (consciously or unconsciously) to death with his shirt. Robotboy angrily demands him to leave Tommy alone. Protoboy complies, though in the worst way possible by dropping Tommy. Protoboy gives Robotboy a choice, save Tommy or the passengers on the cruise ship. But Robotboy manges to save both by saving Tommy in time, putting him safely on the deck of the cruise ship, and then saves the cruise ship by going underwater and smashing the surface to make a big hill for the ship to rest on. Protoboy is impressed by this, but still wants to fight.
This makes Robotboy having no choice but to fight him and they superactivate, Robotboy gets unusually defeated quickly by Protoboy, much to Tommy's horror and sadness. Protoboy proclaims he got his revenge and prepares to destroy the whole ship, commenting on how he would have liked to have seen Robotboy see him destroy the ship and kill everyone on it, but suddenly Robotboy comes from nowhere, leaving Protoboy surprised and Robotboy reaches to his chest and tears out his motherboard. A down-faced Robotboy watches his brother falling into to the sea, obviously hurt about how he had to kill his own brother. He brightens up when Tommy is happy see see him alive, Robotboy turns around to see his friend Tommy being unharmed and explains to him that he played possum like Gus taught him and they fly away to find Gus.
The episode ends with Donnie catching a shark on the fishing boat. When the fisherman takes a picture of Donnie and the shark, Gus comes out of the shark. Upon seeing Donnie he plays possum, causing Donnie to panic again and jump in the water to swim away very fast.

- Some fans are confused when this episode takes place. Either after the events of "Brother" or "The Old Switcharobot", particularly when Tommy says to Protoboy: "You were blown to bits, I saw it with my own eyes!" As he was blown up in both episodes. This episode being produced before the latter confirms that this was intended to be Protoboy's second appearance.
- Protoboy's line "Okay, Proto have no time to finish you, but Proto be back". This line is a possible reference to the famous line said by Arnold Schwarzenegger from the movie "The Terminator": "I'll be back.".

- Goof: When Protoboy was holding Tommy to show Robotboy the "Bad thing" he did, the wires on the front of his head were missing.
- Goof: When Donnie says "get up you big faker!", a small dot appears briefly above him.
- Possible Goof: This might be an angle thing, but Robotboy and Protoboy are just about to punch each other, Protoboy's upper half appears to be dislodged from his lower half.
- While Protoboy is holding Tommy with his shirt, it's appears that Protoboy is choking him. Because he is lifting Tommy with his shirt, causing Tommy to slowly choke as seen by Tommy's expression.
