Using the Dragon Radar that Bulma made, Goku easily spots the Dragon Ball that drifted down the river. However, Kinto'un is blown away by Captain Silver’s bazooka! After defeating Silver with a single swipe of his tail, Goku heads north in a plane flown by a robot who came out of a capsule. Goku shudders from the extreme cold. The robot is frozen solid as well, and the plane crashes!! Having been frozen solid, Goku is saved by a girl named Sno.

Goku wakes up in Sno’s house, and receives gentle care from her and her mother. Sno is frightened when she hears that Goku is searching for the Dragon Balls. In this village, General White of the Red Ribbon Army has taken the mayor hostage, and is using the townspeople to search for a Dragon Ball! After regaining his health, Goku defeats the soldiers who came in pursuit of him, and heads for General White’s base, Muscle Tower, in order to rescue the mayor! After defeating the soldiers outside, Goku immediately thrusts himself up to the second floor!!

General White’s voice resounds throughout Muscle Tower. He provokes Goku as he ascends to the uppermost floor, where the mayor is. Goku defeats the soldiers on the second floor, and advances on to the third. The third floor was protected by the immortal giant, Sergeant Metallic! Goku has a hard battle against Metallic, who rises up again no matter how many times Goku knocks him down. He won’t stop, even after having his head blown off with a Kamehameha! It turns out he is a robot!! However, Metallic stops just as Goku is in a pinch. His battery had run out.

After infiltrating the pitch black fourth floor, Goku is hit by Master Sergeant Murasaki’s ninja attacks. He has a difficult battle against these relentless attacks! But Goku reads Murasaki’s movement, and his attacks turn the situation around. Goku breaks through Murasaki’s ninjutsu, one after the other. Finally, Murasaki’s sword breaks! Murasaki challenges Goku to an unarmed match, and Goku puts away the Nyoi-Bo. Murasaki takes advantage of this opening to throw a boomerang shuriken. Goku is caught off guard, and is hit directly in the back of the head!! Goku is in grave danger!!

Unable to finish Goku off with the boomerang shuriken, Murasaki uses his final ninjutsu, Bunshin no Jutsu (Split-Image Technique). Having somehow increased to five people, the Murasakis each take out their different weapons! Unable to tell which of them is the real one, Goku has no choice but to run! However, it turns out the Mursakis are merely a set of quintuplets. Now aware that they are all real, Goku uses Zanzouken to defeat four of them in the blink of an eye. With no other card to play, Mursaki calls forth Artificial Human No. 8!!

Artificial Human No. 8, who Murasaki summoned, turns out to have a gentle personality, and doesn’t like conflict. As Murasaki is about to destroy No. 8, who won’t listen to his orders, Goku blows Murasaki away with a single blow! Now Goku’s friend, No. 8 (Ha-chan) leads him to the uppermost level, floor six. Ha-chan tries to persuade White to stop doing bad things. But Goku and Ha-chan fall through a trap door to the fifth floor. Down there is the lair of the monster Buyon!!

Imprisoned on the fifth floor, Buyon is a monster who is completely unaffected by Goku’s techniques! His body can absorb any attack. Goku is in an absolutely desperate pinch!! But Goku destroys the wall, having remembered the time when he was frozen!! Buyon is frozen solid by the frigidly cold air!! After enduring the frigid air by huddling close to Ha-chan, who is immune to the cold, Goku manages to shatter Buyon with a single blow!! Returning to the sixth floor, Goku attacks White.

After being beaten up by Goku, White guides the two of them to the mayor’s room. The second Goku and Ha-chan let their guard down, he takes the mayor hostage! Ha-chan doesn’t know what to do. Goku is downed after being hit with a single shot from the powered gun!! The second shot will finish him off. However, Ha-chan acts as a human shield and protects Goku!! With White in a panic, Ha-chan’s punch explodes!! Having saved Goku and the mayor, Ha-chan destroys Muscle Tower.
