Principal Kirkpatrick announces that he's holding a trial for a dangerous alien at Galaxy High. "Alien dignitaries from around the universe will be in attendance, including a witness, King Fypon." Josh, Brett and Yoko are all ears when Kirkpatrick tells them that they have a very important role in the trial. But their anticipation quickly turns to disappointment when they find out that their assignment is to look after the King's son, Fypon Jr., whose babysitter canceled at the last minute. When the gang first meets the seemingly innocent alien toddler, they think that their assignment may actually be kind of fun. But once the adults are out of the picture, Fypon Jr. proves to be quite a handful. The moment he's alone with the team, he begins to cry... an ear-piercing, glass-shattering, alien baby cry!
