Despite Roll's possible mastery over all things gassy, Alt manages to outdo Roll's fart by a few seconds.
Roll giggles a little. "Alright, you win. Now, what are we doing next?"
Alt grins. "Well, you said we'd do anything I want, so, I say we're going to play this game forever."
"W-what? Are you serious?" asks Roll.
Alt nods. "I am. I mean, we're having lots of fun, aren't we? I say we seal ourselves in the room and do nothing but play the dice game."
Roll only has to think for a second. "Ok, I'm in! But what about everyone who knows me?"
"Heh, I'm not going to tell you how exactly, but I've made it so that nobody besides me knows who you are or that this room exists." says Alt, with a tone of sincerity to her voice.
Roll smiles. "Ok, I trust you. Since that's settled, I guess we have nothing left to do but keep this room sealed off and then keep playing our game forever."
Alt nods, and goes over to the only door to the room and welds it shut. As soon as she does so, their surroundings turn to a light red color.
Roll blinks. "Wh-what did you just do?"
Alt grins. "There's a new rule to the game from now on: Every roll causes the particpants double in size. As you can imagine, we're going to need all the room we can get!"
"Ooooh, double? Wow, we'll be really huge only after a few games!" Roll happily exclaims.
Alt nods. "So, are we going to stay tiny or are we going to get started?"
"Take a wild guess!" shouts Roll, before giggling and taking a roll with Alt, the two growing to 200 feet wide, just as she said.
With their size constantly doubling and the randomness of the game, the girls never had a dull moment again, as they blissfully played their game until the end of time.
