Dragon ball z: Time Travel mix up

Even more trouble. We can't catch a break now can we?

Goku:

It had been been a week and a half since the girls disappeared with the time machine and everything that could go wrong was going wrong. Bulma had figured out that she no longer had the correct pieces to construct the time machine. She said that she had used a bunch of scrap pieces from one of the sayian ships to build it and that there were not enough high quality pieces left to build a replica time machine. Since then Bulma had been messing around with pieces of equipment in an attempt to improvise for the missing pieces but she hadn't come up with anything yet.

I sighed and leaned agianst the wall. Even with Trunks and Gohan's help we weren't making much progress. Vegeta and I had returned from our quest of gathering the dragon balls several days ago and Vegeta still wouldn't tell anyone what his plan was. When I had asked him once we had gathered all the dragon balls what his plan was he had shot me an angry glare and told me that I would know soon enough. Since then I have been awkwardly hanging out in the lab, helping out with whatever I could, but considering I didn't know much, if anything about computers I wasn't much of a help besides helping with the heavy lifting.

“ Kakorrott come with me.” Vegeta suddenly ordered, walking away from where he was helping Bulma and gestured for me to follow. I obediently followed him out of the room and down a series of hallways.

“ Vegeta where are we going?” I asked, getting ready for Vegeta to either A yell at me or B shoot me an angry glare. Probably both.

“ It's time to use the dragon balls. I'll tell you what the plan is now, considering you are going to be a large part of it.”

I stared at Vegeta's back, with a confused look on my face.

“ How can I help Vegeta? You know I'm no good with electronics, so I don’t know how I can really help.....”

“ Shut up kakorrott and listen!” Vegeta snapped, not even bothering to look at me.

I shut my mouth quickly and allowed Vegeta to explain his plan to me.

“ I remember you once mentioning some room called the pendulum room. It allows you to go back into the past, correct?”

“ Oh ya. I went there once as a child. I completely forgot about that.”

Vegeta nodded to himself.

“ Good. Then we can go there and go back into the past and get the parts needed for Bulma to make another time machine.”

Hmm that was actually a good idea. I was pretty sure that you could take something from there. Though I don't think humans counted. That was probably why Vegeta didn't plan on using that room to retrieve the girls.

“ Oh that's a good idea Vegeta.” I chirped. It was nice to hear some good news for once since the girls left. Chi Chi had been very out of it and depressed since Goshe left and I didn't blame her. Everyone had been down in the dumps since their disappearance, including myself.

“ Of course it's a good idea you idiot.” Vegeta grumbled.

He stopped suddenly and turned to look at me. I stopped too and looked at Vegeta questioningly.

“ But what are the Dragon balls for then?”

“ Well we will be going back in time to a few years before Planet Vegeta blew up so that means that we have to look like a sayian. It's the only way for us to get the pieces that are needed to finish the time machine.”

I stared blankly at him. I still didn't understand how the dragon ball's came into all of this.

Vegeta sighed irritably at my blank expression and slapped his forehead with the palm of his hand.
