Here's what you need to know about RePOOPulate!

• We all have bacteria in our guts that help us digest food.
• Sometimes, one species of bacteria takes over our guts. It's named "C. diff" for short, and when it takes over, diarrhea and sickness result.
• Getting good bacteria back in the guts is called "probiotics." And Canadian scientists have come up with "fake poop" that they can stick in a person's guts to get those probiotics in shape.
• FINALLY, this is the cool part. They call this fake poop RePOOPulate!
