You decide to rescue your family and friends

The red pen is in your hands. With some trepidation, you press the button gingerly. It's anticlimatic, but nothing happens. You press it multiple times and aimed at various things such as yourself and blankly into space but nothing happens.

"Piece of junk," you exclaim as you slouch back into the couch. You can't believe that the last one was a dud and you fume silently, Gabby's normally serene face screwed up with a mixture of disappointment and rage. As you lay there thinking about all the lives you have borrowed, you accidentally press the button on the red pen absentmindedly. To your surprise, your body starts to swell until you reach a sizable girth. In shock, you run to your bedroom where your full length mirror is, heavy foot steps along the way, where you see Gabby's normally slim athletic body has expanded to overweight proportions. In fact, you look like the splitting image of....

"Lucy!" you shout, half in shock and the other half in fascination. You think back and realise the moment that you pressed the button, you had been thinking about Lucy and were wondering how she was. The image in the mirror definitely looks like Gabby but with Lucy's figure. That's what the red pen does! It provides the user with a way to modify the skin's parameters but to what limits? This is what you have to test. Soon, you have seen Gabby in many different forms. Fat, skinny, anorexic, obese. Whatever body shape you can image, that's what you become. But it isn't limited to that. Hair colour, hair length, hair style, eye colour, skin colour even. There are it's limits though. You can't fundamentally change your appearance too much to become someone else. Just imagine if someone received plastic surgery, that would probably be the extent to how much your host's structure can change. Therefore, things like height are out of the question but even with its limits, you're amazed at how different you can make Gabrielle look just from the few things you can change.

After you've restored your Gabrielle form to its original state, you start to plan. You have five pens. The black one turns anyone hit with it to turn into a wearable bodysuit. The brown one gives you their mannerisms, parts of their personality and muscle memory and surface level facts about them. The blue one transfers all their memories into you, provided that you're wearing them at the time. The white one is a hypnosis and skin stripper. The red one allows you to modify your skin's body at will. Your use of these will be invaluable to helping you retrieve your loved ones.

Loved ones? Is it really possible for you save them all? Or should you pick and choose who you want to go rescue? When would be best to do it? These are questions which you mull over as you plan your escape.
