Johnny slowly walked up to the door with his massive stomach, and holding it up with his hands. Johnny then realized he was in more than a tight spot, and that he had to duck down too in addition to squeezing his fat gut though, due to his increased height. Johnny sighed and began ducking into the doorway, and was able to get his main body through, but his massive gut was still stuck inside the doorway.
"Damn it! Why didn't I go with someone else, so they could help me with this thing!" Johnny growled, and began tugging at his gut, but it wouldn't budge.
"And now I'm stuck, Johnathan the humanoid fat T-rex is stuck in a doorway." Johnny said falling down to his ass, and tail.
"Wait, Johnathan?" A voice said, and a ferret came running up to Johnny.
"Yes, and you are?" Johnny asked looking down at the ferret
"Johnny it's me Ryan, your brother, and you're...I'm not going to ask." The ferret, Ryan said
"Wait Ryan? How?" Johnny asked
"Long story, but considering you're like this now I guess yours might be more interesting to hear." Ryan said laying down on his stomach.
"I drank a potion, and burped multiple times, and this happened because of it." Johnny said unamused
"Wait, that's it? Wait why burping?" Ryan asked
"I don't know things happened when I burped okay. Well for once I hate to be called big bro." Johnny said
"Well I don't know about that second thing, but maybe passing some kind of gas helps you transform, or something. Try to induce burping, and I'll see if I can do anything on the other side of you...don't misinterpret that." Ryan said
Ryan then crawled onto Johnny's muzzle and jumped onto Johnny's ginormous gut, and moved to the other side. "Geez dude how much did you eat after transforming?" Ryan called over
"Not funny! I haven't been able to leave the room." Johnny growled
