As the two saiyans were inspecting the machine, Bulma went into the room. she saw the two males inspecting her new device and screamed at them.

"What are you two doing here!"

Goku and Vegeta jumped in surprise, looking at their blue haired companion standing angrily by the door. Vegeta was the first to gather his wits and replied "The lab door was open woman, Kakarot and I were curious on what crazy invention your building this time...and, as it says in the blue prints, it's a body switching machine."

"Were did you... just dont touch anything ok?" Bulma said to the prince.

"Anyway what's the reason for building it Bulma?" asked the orange clad warrior.

Bulma sighed annoyed and explained to Goku and Vegeta what it was for. When she finished her explanation, Goku and Vegeta looked at eachother in surprise, Goku went back and started to reexamine her invention while Vegeta remained, talking to Bulma.

"Why on earth will you build a machine for body switching?"

"I already explained it to you it's for...Goku no!" Bulma shouted, he saw Goku, finger about to press the big red button that turns on the machine.

"Huh? What is it Bulma?" asked the taller male.

"Don't touch that button!"

"Why?"

"That's the start button! I didn't test it yet! So i don't know what will exactly happen if it turned on!"

"Oh really? sorry, I didn't know." he laughed nervously and rubbed the back of his head.

"It's ok... Anyway let's go to the backyard and eat i'm starving!" the blue haired genius said, as she streched her arms, loosening all the tight muscles she has used to work on her machine.

"You didn't eat woman? How long were you working on this invention of yours?" asked Vegeta.

"Since..uhhhh... 4 in the morning."

"Wow that long!" Replied Yamcha.

"Yep! Anyway lets go! im still hungry here you know!"

After leaving the lab, everyone headed outside. Bulma started to cook on the grill near the door, Yamcha was helping her, though not much, Goku was setting up the chairs and tables in the back and Vegeta toke Trunks to train in the gravity room to pass the time. When 3 hours has passed, Vegeta called an end to their training.

"Trunks, take a bath I don't want your mother complaining to me why you smell."

"Alright daddy I will." The purple-haired demi said gladly. with no hesitation, he rushed to the Bathroom. Vegeta decided to see his mate to check if there finally done with lunch. He was headed back to the backyard when he saw Bulma in her lab, under the body switching machine, fumbling with and that. The prince went inside, without making a sound, and stopped at the feet of his ex wife.

"Bulma, we need to talk."

"AHHH!" Startled, Bulma jerked her head upwards, hitting her forehead on the machine. Her head throbbed as she groaned in pain. She heard light chuckling coming from a voice she new so well. "DAMMIT VEGETA! DON'T SCARE ME LIKE THAT!"

"Huh?ME scaring you?By now I thought you were use to it." He laughed.

"OH ha ha ha" Bulma replied sarcasticaly.

"Anyway I need to talk... it's about your invention."

"Oh no, not this again. why can't people just accept the fact that i'm building a body switching device instead of giving me all types of bullshit like... ohh Bulma why are you doing this? what are you thinking? are you crazy? and blah blah blah! why cant you guys just leave me alone and let me work on my machine huh?"

The prince can see that she was stressed out and placed his hand on her shoulder "Damn woman, you sound really stressed about this. The only reason everybody's saying this because there just want to make sure that what your doing will be ok."

"But Vegeta i'm 94% positive that it would work." She said.

"And how about the the other 6%?"

Bulma didn't say anything. Then vegeta lifted her head and said "You see? that is what everybody is worried about. the side effects it I always hated to see you like this and you know that, how about you take a whole day off and have a breack from all this?"

Bulma starred at Vegeta and knew he was right and decided to take his word for it, so she nooded and stood up.

"ok, thanks Vegeta",Bulma smiled.

"No problem woman, now let's go to the backyard and eat."

Bulma noded and followed Vegeta to the back of her house. They have just arrived when Chichi came with Goten.
