You and TestTube had some sort of motherly bond! Though TestTube technically built you! Through fan's knowledge and her invention skills. You were made.

You both walked through the mall, TestTube holding you hand as she rambled on about some sort of new invention she would build in her 'secret' lab. The bright lights and nice AC stood out to you.

"-Ill make sure to put in the advancer, definitely not letting Fan touch it haha!"

She rambled too herself, patting your head as you both walked. Passing many shops.
