It happened during "Mickey's Not-So-Scary Halloween Party" on Sunday.
Erick Comellas, the person who took video of the moment, posted on Facebook: "The brave cast member who slayed the wind monster in this video is okay!"
Comellas tagged Brandon Myers in the video; he's identified as the balloon handler.
Myers was able to hang on and prevent himself from becoming a real-life version of Pixar's "Up."
