A new rule stating "If it exists there is inflation art of it" no exceptions. This rule can be used in many inflation scenarios including but not limited to: Body inflation, Blueberry Inflation, Head Inflation, and many more. This also means if there is not any inflation art to a certain fandom or IP there will be.
"Bro why the hell is there Sonic inflation porn?"

"Oh you mean Rule 91?"
