You spotted a computer desk top on one of the tables and lunge for that. Your body engulfs the machine and you feel your self absorbing the device.
Your blue slime body and the nano bots work in perfect sync in dissolving the computer. As you consume it in your body, you learn from it. Memorizing each piece of the device as you break it down. Consuming everything down to the memory. (Someone kept a porn folder here.)
Once the computer is gone you still know how it fits together perfectly from the blue prints stored in you.
You reform your body in the shape of the computer you just ate. The outside is a hard plastic shell with the inside being totally made of slime, but you can still work the screen and keys, and kept all the memory stored, also if someone decides to open it if you want you can make the inside metal. You slip a wire to the internet connector for extra realism.
You put on the finishing touches and wait to see who enters the lab now.
