it was impossible to estimate the size of the creature, it was elastic in size and could stretch out and fill any shape, like an octopus. people had recorded it in a human form, walking bipedal. there were u tube video's that showed the enzyme in a shopping mall, it was shot on a galaxy 11 smart phone. a silhouette figure walking into a westfield, initially a small crowd just stare but moments later panic spread. hysteria kicks in. you can hear the screams, see the look of panic in peoples eyes. whomever holds the camera phone must have nerves of steel, they hold their ground and film the enzymes movements, from slightly higher, maybe a platform of stepladder. 

the thing is constantly shifting, made of liquid yet solid, parts of it stretch outwards, it glides along the floor and the two legs seems to sometimes merge into one pillar, which acts as a base.

it moves a few meters into the complex and then suddenly an limb stretches out, smashing through a glass window and the creature then follows it like a giant slinky toy. it's no longer in the camera frame but we can see and hear a bizarre slurping noise as though pumping liquid fast. in some frames we can actually see the surface of it's skin throbbing as it ingests.

we know these things were originally designed to absorb non biodegradable plastic, an australian / french biotech company developed it in 2018 and the first enzyme was released into the ocean in 2019. a few months later a fishing vessel returned into a newfoundland harbour with three dead crewmen and a damaged stern. the survivors claimed a black sea creature had been trawled up in the nets and attacked them but no one seemed to believe them. 

after that a few sightings became urban legends, seafaring mythology. 
occasionally one of the late night news channels would run a sensationalist story but then the sightings became irrefutable and then a common occurrence. much like shark sightings, the enzyme creatures inhabited secluded spaces, avoiding human populations until they cleaned up the oceans, cleaned up the forests and wilderness and then on the hunt for plastics started migrating towards the cities. 
governments created an industry designed to terminate them, but nothing seemed to kill them, extreme heat, cold, bombs, poisons, gases and radiation all were ineffective. 
the p e squad or pee squad as they were known amongst the more cynical were able to relocate the enzymes but that was all they could do. there was talk of entrapment, in a sealed chamber and then the chamber launched into the sun but so far this was just white noise on the net.
in the video the enzyme now appears as a pool flooding out from the shop and then assembling itself as a human shaped figure about 7ft tall. it marched towards the next shop it could find that stocked plastics and repeated its absorption. the camera man then starts descending. 
we see the creature in a children's toyshop filmed from behind it is now a blob standing upon one large column leaning into a stack of plastic infants toys. the body pulses with it's rippling effect, the sound of slurping gets louder. a strange tentacle buds from it's back and shoots across at the shop front opposite, a distance of several meters. it smashes through the glass and starts sucking on some plastic boxes, absorbing the material. another bud begins to form, the camera then backs away fast. we hear heavy breathing and see the various viewpoints as the camera seems to trace the walkways, then the face of someone still running, obviously holding the camera. 'fuck, it's chasing me, i'm going to...'
the camera phone is now thrown forwards and it bounces on the ground before coming to a standstill.
we can't see much, just the ceiling but we can hear screaming. a black shape slides by.
there are many other videos but that seems to capture the enzyme best, it shows how it has grown and how it moves. plus it's the only one that offers proof that it is able to take the shape of a human. 
underneath the video we read the cameraman was a man called oliver z ramoz, and his body was found torn to shreds in the mall in various places. they say a pee squad arrived on the scene about an hour later and by then the creature was gone. it was never found and remains at large.
plastics have long been banned, but so have the enzyme that eats plastics. it's just a matter of hunting them down. 
there are several eyewitness accounts of them recreating themselves by splitting apart like an amoeba although no footage exists. 
authorities speculate the only way to get them under control is to starve them of plastics. 
there's another video of some children in norway whom create a trail of plastic bags and them film with another phone camera. the enzyme (a smaller one) following the trail, absorbing each bag as it approaches. they lead it into a glass trap and then alert the authorities. this idea catches on amongst the young and across europe and north america children begin to devise traps for the enzyme, but the enzymes seem to develop some sort of morphic resonance and learn how these traps work, eventually children are killed and the practice banned. 
in my communion with the whales over the last few months i have accessed information which i believe will help combat the enzyme, the whales are very grateful for human intervention into cleaning the ocean, they have told me there are no traces of plastics left, which is why the enzyme is on land. 
the whales are ancient strange creatures, they sing songs and collectively dream. although they have no technology they have mindware. the problem is mindware in whales only works in harmony with peace and tranquility, it is not possible for a whale to use it to create harm. but a human, a human is destructive in nature and can use mindware in combat. they download the thinking technology into the in-qubit, it feels like a rush of wind inside my neo cortex.
