Red Lactic Acid Bacteria

Lactic Acid Bacteria are small, cute characters from "Cells at Work!" who first appeared in Episode 20. They look like penguin-shaped wobbling toys, each with different colors and patterns. They make a "nyu-" sound and play an important role inside the body by fighting harmful germs and eating purines. Lactic Acid Bacteria help keep the body healthy, and each type lives in a different part of the digestive system, doing special jobs. Sometimes, they even help activate immune cells during infection. Their friendly and quiet nature makes them lovable, and they're often seen as adorable mascots in the story.
