Jamie was feeling very apprehensive, as she followed Marlene into the lab. She was worried about getting in trouble with her grandfather, but Marlene had insisted on checking his lab out.
'Shhh, Jamie,' Marlene whispered, 'I think this is your grandpa's lab. Let's sneak in here, and see what we can find.'
'Grandpa tells us we're not supposed to ever come in here,' Jamie said, nervously.
'Well, you know, he's spending the week in Jamaica,' Marlene insisted. 'Gee, I see a lot of strange treasures in here. Maybe we can find something that's useful to us.'
'Well, I see a station wagon and an old DeLorean in here,' Jamie said, looking around. 'I wonder what he wants a DeLorean for. I heard they were very high-maintenance.'
'Hey, lookie what I found here!' cried Marlene. 'These are called invisibility shields. I wonder if these things really do make you invisible. It would be so cool if these things really did work. Just think of what all we could do.'
'I suppose we could try it,' Jamie said, quietly. 'There are certainly times when I wish I was invisible, you know. I mean, I'd rather not be noticed at all - than constantly get picked on. I mean, it hurts when other people are mean to you.'
'Well, let's slip this things on, then,' suggested Marlene. 'I wonder where you grandpa picks these things from anyway. I think he has a few tricks up his sleeves.'
As Marlene and Jamie slipped into the invisibility shields, Jamie noticed that the fabric felt like something she had never seen before. Jamie then pressed a button on her suit, and an automated voice said, 'Size adjusting. Fit.' She then pressed the other button, and it said, 'Invisibility mode on.'
'So, Marlene, does this really work?' asked Jamie, a bit uncertain.
'Well, I can still see you,' replied Marlene, 'but it's maybe because I'm wearing one of these, too. Here, let's stand in front of the mirror, and we'll check.'
Jamie nearly fainted, as she and Marlene stepped in front of the mirror. She couldn't see their reflections. Perhaps, the invisibility shields really were working.
'Hey, this is our chance, y'know?' suggested Marlene. 'Let's sneak into Griff Tannen's home, and we'll punch him out. Think it will maybe scar him for life?'
'Oh, I can think of many people I would like to get back at,' Jamie said, smiling widely. 'I suppose we might as well start out with Griff Tannen, though.'
Jamie and Marlene then left the lab, as they headed over to the Tannen's home. They were careful to avoid running into anyone, as they didn't want to scare anyone.
oooooooooo
As soon as Marlene and Jamie arrived at the Tannens' home, they crept into the front door. To their horror, they saw that Harmony and Melody were bound and gagged in the living room. Marlene and Jamie then turned the invisibility mode off, as they went to rescue the girls. As much as Jamie was often jealous of her older sister, she did love her sister dearly, and she would be horrified if anyone laid their hands on her sister. Her heart was beating wildly.
'How, uh, where did you come from?' asked Harmony, stunned.
'Yeah,' chimed in Melody, 'it's like you two just formed out of thin air.'
'Oh, it's these suits we're wearing,' explained Jamie. 'They make us invisible. Don't ask me how. I don't know. So where are Griff and his gang? We'll have to get you guys out of here!'
'They went to rob the Courthouse Mall,' explained Melody. 'Thank you so much for rescuing us. Can you rescue Marty, too? He's at Spike's house. I'm afraid she might be harming him. Man, I am so concerned for my brother.'
'Sure, we can do that,' replied Marlene. 'Why don't you two head over to Doc's lab, grab the station wagon, and then pick us up? Then we can decide where to go from there.'
'Okay, then,' replied Harmony, as she and Melody slipped out of the house.
Marlene and Jamie then turned the invisibility mode back on, as they headed down the next block to Spike's house.
oooooooooo
As Marlene and Jamie slipped into Spike's house, they heard the sound of someone laughing helplessly. As they followed the sound of the laughter, they discovered that Spike had Marty Jr restrained on her bed, and he was relentlessly tickling the soles of Marty Jr's feet.
Ordinarily, Marlene would be amused by this, as she knew Marty Jr had extremely ticklish feet - and she had been known to tickle them relentlessly, from time to time. Still, considering that they were dealing with a member of Griff's gang - she knew what needed to be done. She punched out Spike, knocking her unconscious. Marlene and Jamie then deactivated the invisibility mode - as they freed Marty Jr from the restraints, and they gently lifted him up.
'Oh, thank goodness you're here!' Marty Jr said, with relief. 'I was afraid Spike would never stop. The soles of my feet are so unbearably ticklish.'
'Yeah, I know that,' Marlene said, smiling.
'Don't you even think about it, Marlene!' insisted Marty Jr. 'I know what you're thinking - and, no, you may not.'
'C'mon,' urged Jamie, 'we need to get out of here before Spike comes to.'
Marty Jr then followed Marlene and Jamie, as they headed outside.
'Maybe another time,' Marlene said, quietly. Marty Jr shot her a dirty look.
As the trio headed outside, a station wagon landed beside them. Marlene saw that it was Harmony and Melody inside the car. The trio quickly stepped in.
'I wonder what these weird gadgets in here are,' Harmony said, stunned. 'If I didn't know any better, I'd almost think this is a time machine. Of course, time travel isn't really possible.'
'Hey, Harmony,' urged Marty Jr, 'I see Griff and his gang behind us. We'd better get going. Let's see if we can get them off our trail.'
Harmony then began to pilot the station wagon as high in the sky as possible, as she accelerated the speed.
'Let's see if you bastards can do ninety,' declared Harmony, as the odometer crept up towards 80 miles per hour.
Then, as the group had reached 88 miles per hour - they broke the time barrier.
