Inflatus is a jinx that inflates creatures.
Behind the scenes
In the video game version of Harry Potter and the Goblet of Fire it is used to inflate Vampyr Mosps, Blast-Ended Skrewts, and Salamanders. When used on Mosps or Skrewts, they burst into colourful party balloons instead of inflating.
The prefix 'Inflate' derives from the English verb "to expand with oxygen".
