What's your earliest memory of Inflation?

Playing Kirby's Dream Land when I was around 4 or 5 years old on my sister's Game Boy.

The ending specially was my first contact with inflation.

An old dutch/belgian tv show about a young witch. I always hope to find this back, but still no luck with that.

There were couple of cartoons that I had strange interest in since I was 2 or 3. I don't remeber which one exactly was the first, so here is the one that I haven't mentioned earlier:

A soviet 1988 cartoon, "Медвежуть" ("Bear Eeriness" or "Beariness"), aside from being a hilarious parody of surrealistic movies, features a storyline where a bunch of animals finds a magical box that gives everyone as much of their prefered food as they wish. Expectedly, they end up stuffing themselves to the brim.

I remember seeing a episode of Teenage Mutant Ninja Turtles titled Michaelengo's Birthday and there was a scene where Leo, Raph and Donny blew up like balloons after getting sprayed with a gas that was suppose to turn them into babies

   I remember seeing a pregnant woman when I was about 4 or 5 years old and thinking that she was gonna fly away like a balloon, so I grabbed ahold of her ankle to stop her from flying away. One of the funniest experinces when I look back at it, but who'd have known that it would've lead to influencing my sexual tastes?

For me, I'm pretty sure it was the old Disney cartoon "The Three Little Pigs".  The way the Big Bad Wolf's chest inflated when he inhaled fascinated me as a kid.  

Another of my earliest memories was a children's storybook of Aesop's Fables, with a really amazing depiction of The Frog and the Ox.  There was a gorgeous watercolor sequence of the frog inflating like a balloon to ENORMOUS size, ending in a full-page starburst of him bursting spectacularly.

After that, it was clips like this: https://youtu.be/_GYvmJXsptE  as well as the scene from the animated Baron Munchaussen movie, where the character Hurricane (the one in my avatar) puffs himself up like a balloon in order to blow up a windstorm.  You can find it here: https://youtu.be/Oy1NpjS08fU  (the inflation scene is at 22:43).

All of these had a huge influence on the evolution of my fetish, and continue to influence it to this day. 

Admittedly, my first thoughts of inflation were not actually tied to any one cartoon or movie. Certainly, once I started seeing content, it just cemented in my mind what I liked, but this is how I think my fetish truly started.

Back when I was five or six, my mother(an avid horse person), would often take her horses to these training grounds a ways away from our house. Rather than leave me at home by myself, she'd have me come along while she trained her horses. Now, she worked during the day, and so only could do this training at night for one or two hours. I remember lamenting those nights because they were all frigid cold. Winter time sucked. Anyways, so one day while I was off sitting and shivering in a chair outside the arena my mother was using, I started to fantasize(more daydream, given my age) about getting away. Wondering how I could, I imagined my jacket and pants all sealing up at the cuffs around my ankles and feet, and just filling up with air. Swelling spherically, floating me into the air, and toward my house, just to get away from having to sit in the cold.

I consider this my first inflation thought, and for the life of me, were it inspired by something, I cannot think of what it would have been then. A cartoon? Mostly likely, but I can't think of a single one that would have triggered it.

I was given an impromptu demonstration of belly inflation by my older foster-brother. 

Yes, it's a really messed up story; no, I won't post it here; yes, I'll talk about it over private messages.
