Inflating Body Gag

"I got hit by an airplane!"

A character inhales too much helium, or other some other gas, and their whole body inflates like a balloon. This usually causes their clothes and hair to inflate as well. This is often inflicted on the character as an Amusing Injury, but some characters will do it to themselves deliberately. Because All Balloons Have Helium, inflated characters are liable to float in the air or blow away in the wind, even if they were inflated with normal air. It often ends with the character deflating just like an untied party balloon, flying through the air and sputtering as the gas rushes out of them. Alternately, the character may inflate beyond their limits, resulting in "Pop!" Goes the Human.

May also be done with water or other liquids, in which case you can expect a lot less floating and a lot more wobbling.

Of course this would be impossible and grotesque in Real Life, unless your character happens to be a Rubber Man or pufferfish. Online, this trope is known for being Fetish Fuel, but let's not go into that here.

Compare Balloon Belly (only the belly inflates) and Temporary Bulk Change or Attack of the 50-Foot Whatever (grow in size but not inflate). Related to Be the Ball. Constrast with Squashed Flat. As a form of Toon Physics, this trope tends to run on Rule of Funny and Willing Suspension of Disbelief.

    Anime & Manga 
  • Used bizarrely in Bobobo-bo Bo-bobo, involving a giant toilet. Whoever falls in, they swell up. At one point, Jelly Jiggler (who fell into the toilet with Gasser) blows up into pieces. He got better.
  • Princess Buburina from Catnapped! has an enchantment on her, causing anyone she touches to blow up into a balloon.
  • One Piece: Luffy uses this as one of his attacks through Gum Gum balloon, sucking in so much air that he turns, quite literally, into a balloon. Worth mentioning is his second fight with Crocodile where he ingests an entire barrel of water and turns into "Water Luffy". He later developed a much more potent version by distributing the air in his Balloon Belly to his Haki-infused muscles, bulking him up considerably and becoming very bouncy. Sounds ridiculous, but this is bona fide Person of Mass Destruction grade.

    Asian Animation 
  • In Pororo the Little Penguin, "Flying Poby" (season 3, episode 20), Tong-Tong uses magic to make Poby the polar bear fly. Then Tong-Tong forgets the spell to bring Poby back down, and accidentally inflates him instead. Twice.
