An extraordinary team of pet-loving superheroes who shrink to microscopic size and enter a pet’s gut to battle the Biome Bandits—harmful bacteria causing diarrhea, itchy skin, bad breath, gas, and hairballs. Using Advanced Gut Microbiome Science, they select the right prebiotic, probiotic, and postbiotic ammunition for each mission, taking on the nefarious bacterial supervillain, Eli Cole (E.coli) and his gang of gut-wrecking misfits.
