"Um well actually that won't work because Yazz doesn't have enough balloons." π€
Flynn just hanging with Yazz at some amusement park... Probably? They would hang here since Yazz likes rollercoasters and the games there and so does Flynn. However, it seems that Yazz grabbed one to many balloons and is flying off. Now she's a Flying Yazz. If Trace does the same thing that would mean he's a Flying Trace, but he probably has too to get her down.
Is this even real? Maybe Flynn hit is head and imagined this. Either way, Mr. Fredrickson would be proud of Yazz.
