Harriet Hippo & The Mean Green

Season 2 Episode 3 | 27m 0s | CC

Hacker infects Motherboard with a new virus - one that causes her to make cyber-citizens do bad things. Digit and the kids go in search of an antidote: 2/5 of the Electro-Root, 2/8 of the Healing Stone, and 1/3 of a box of Hacker's wig gel - a strange antidote indeed! Will the young cyber-heroes be able to gather the ingredients and properly mix these odd fractions before it is too late?
