Toby accidentally hits Blinky with a dangerous gum-gum artifact that de-ages him into a baby troll. Now Jim has to help babysit at the same time as keeping up with his duties at home and as the trollhunter. Claire and Toby search for a way to reverse the spell and discover that Aargh has no clue how to care for babies. Takes place between episodes, right after Jim's defeat of Bular. I don't own Troll Hunters, just this story.
