Not sure which you mean, so here's the two:
In terms of how they pop, either overinflation or a deliberate puncture. Both are a ton of fun, but it depends on which works better
For what happens to them, I prefer the "rubber scraps like confetti" style. A good mix of the potential permanence while not going overboard and ruining the fun.

I have an answer or this, but I won't lie, this feels less like a question and more of an attack, so I don't really feel comfortable answering.

That is... a good question. I think at this point, he can only get to about room-filling size right now. If I felt like it, he could get to house-sized. But room-filled is kinda my perfect size.

Oh, I got a few~ Wanna keep the specifics a bit of a secret, but one is an accidental popping while the other is more on the line of Alexisraine's work~

Hmm. Fwoomph, cream, and Blam!

Well, writing of course is first. But I also would love to make video games, but sfw and nsfw. But I can barely navigate a start-up menu, much less actual code.

Oh jeez.
1. Inflation (Particularly Air is a favorite)
2. Popping
3. Belly and Belly button stuff
4. The thing that gets locked behind my locked and Ao3
5. Hm.... Probably a tie between Inflatable stuff and Looner stuff.

Yes
