Whoops.
Try to summon myself back into the movie theatre. Hopefully I won't be committing the mind equivalent of matter-antimatter contact.
Well, you summon yourself back to the movie theatre, but you're further away from your original seat and there's an even larger and fatter version of you sitting in front of you and blocking your view. You lean to the side to see past your enormous girth and try to view the movie that way, but it feels uncomfortable.
During your adventures in non-existence, our scientist protagonists have entered a cave, presumably the result of their investigation into the rocks.
"-excavated recently?"
"No, not excavated. Look at the ground. No footprints besides ours. And look at the walls. No pick can leave rock so smooth."
Steve stops talking and takes a look around with the I-have-a-fishook-in-my-eybrow look.
"No, something else happened here."
"Eh, you're overreacting, as always. It's probably just a natural cave. Maybe if we're lucky, someone is smuggling fans and has hidden his stash here."
After another small delay of just looking around, Steve orders:
"Check the instruments."
"Still as cold as where I'd like to be right now."
"Come on then, let's investigate further."
With that, Steve activates his bulky flashlight and begins going forward. Dan does the same a few seconds later and reluctantly follows.
As you see Steve from behind, you notice that he has a pistol holster attached on his belt that wasn't there before. Probably a fight scene coming up.
The two continue going through the cave for a while. The camera angles are kinda terrible and everything is dark so you aren't sure about where exactly they are going or what the cave looks like, other than that it's rocky.
Your back is beginning to hurt, leaning like this, and the vaguely defined person sitting next to you is staring at you angrily from time to time with its vaguely defined eyes, probably annoyed you invaded its vaguely defined personal space.
The two finally stop moving and continue to inspect their surroundings and wave their "scientific instruments" around in what the actors believed was a scientific manner: like butterfly nets.
Steve accidentally hits some loose rocks with all that waving, causing them to fall to the ground with a loud bang.
Dan jumps and emits a surprised gasp in response. When Steve turns to look at him, Dan tries to look calm and composed, trying to hide his fear.
"Uhh, find anything Steve?"
"Nothing. Dead end."
However his fear only becomes more obvious as he jumps in surprise when the sound effect of a Geiger counter begins to play.
"Steve!"
Steve rushes to take a look at the large rod Dan is holding in his hand, presumably what the people in charge of props thought a Geiger counter looked like.
"Dear God! That must be more than 1000 rems per second! Good thing it's intermittent or we would had been fried!"
Very few audience members facepalm.
"I dunno, with all this heat I'm already feeling a bit singed."
Steve seems to do some quick thinking before taking the lead.
"Come on! This way!"
Dan reluctantly follows.
"Let's just find what we came here for and get out of this giant radioactive oven!" he shouts to Steve.
Sprint towards it, use biomass to become a crocodile, and latch on to a leg, biting down and shaking my head around.
You begin running towards the creature and it begins to do the same, albeit in a very unusual way. It pushes its central sack forward, absorbs its back legs and at the same time uses the mass gained to grow a new pair of front legs, using the two remaining pairs of legs to support itself. And then it does it again. And again. It moves towards you with incredible speed in a wobbly but straight line.
Undeterred by this, you slide on the ground, allowing your momentum to propel you while your body changes. You have not fully transformed yet when you meet, but you have your mouth and your tail, and that's all you need.
You open your mouth, aiming for the right triplet of legs but when it snaps closed, it catches nothing but empty air. The thing managed to partially absorb your target and move it out of the way. Which leaves you right under the creature.
You try to scurry away with your still forming legs and almost succeed. The creature manages to absorb its legs in time for it to land on your tail, but you manage to pull it away before it can... do whatever that thing does to the tails of crocodiles. Not really sure what that is. Presumably, it's something bad.
The creature, now only a semi-transparent faint blue blob with a shimmering outline like it was when it was first summoned, is currently right behind your crocodilian body.
