Don't Drink the Water

Growing weak with old age, Hex is seeking out something to make him stay young. At the same time, Max is having difficulties with his aging body, so he decides to impress his grandkids at a fair to show them he's not as elderly as he seems. At the dunking game Max challenged them to, he and Ben both get splashed, unaware that the water is from the Fountain of Youth. Max regresses into a ten-year-old while Ben becomes a four-year-old. The booth's owner is the guardian of the fountain, having been charged to do so by Juan Ponce de León 400 years previous. Hex manages to force the man into revealing the location of the fountain, which he uses to become young again. However, Ben uses Heatblast to vaporize the fountain, in the process exposing Hex to enough of the water to turn him into an infant. With the fountain gone, the man reveals that the effects of the water will wear off without constant exposure. Meanwhile, Charmcaster finds her infant uncle and enjoys taunting him at his expense.
