Yellow Face says that Bubble Transformers are a way to get "smooth and soft" skin. However, the Bubble Transformer turns anyone who uses it into a bubble (because, as stated by Yellow Face, bubbles have super smooth skin). Unfortunately, as a side effect, whoever is turned into a Bubble will pop, and since no personal Bubble Recovery Centers are sold, they die, which would make it a reason not to buy it.
- It looks identical to the Box of Paper Slips.
- The Bubble Transformer is the first product advertised by Yellow Face.
