As a proud prospective and self-proclaimed scientist, Test Tube devotes her life to the education of science. Test Tube has an extreme form of atychiphobia, or the fear of being wrong. She is usually happy or at least neutral, and is somewhat silly as well, and is always pleased to share her scientific knowledge. She isn’t that good with socializing, but that’s fine. She says words like ‘jeebweezer’ and golly,’ etc.
