I just finished a game for my Oculus Rift called (see title), and it has this really neat gimmick. See, at the start of the game you are crawling through the grass and you see Finn and Jake. They see you and go to say hi, and shortly after Magic Man (antagonist of the series?) decides to have some fun with you and inflates you like a balloon.
(It's actually to give you a reason to exist in game as a high camera angle. Works well as Jake constantly interacts with you).
Ok, you don't actually get to watch a physical body inflate, but you hear the sounds and your viewpoint goes up with every pump (think if just your head inflated).
All in all, it's a pretty fun, but short experience. I just wanted to let y'all know that yes, there is a game you inflate in, POV style.
Here's a Youtube video of a girl playing it:

When "Magic Man" appears she gets so excited that starts laughing loud, which makes it difficult to hear the sounds(altough is nice seeing her enjoing it so much), but pay attention and replay that part and you'll notice the "balloon expanding" sound effect (don't expect a helium tank, a spell is thrown at you).
