Alien Biomass Severity Warning System

You ever have a dream where you get so mad at the sheer incompetence or stupidity on display that you halfway wake up and think about ways to fix it? I just had that.

I was dreaming that a new unidentified bunch of goop that clung to the ground appeared at a coastal city. It was pink to skin colored, and was thought to be alien, appearing along the beach and ocean-front caves. The news made a big deal about how they don't know how it spreads, if it's dangerous, or what it feeds on, when there was a VERY OBVIOUS shadowy indentations just underneath the biomass that were human shaped. I took the picture off the website and opened it in mspaint or photoshop and outlined the shadowy bits that poked out from the smooth biomass floor, and very obviously got human silhouettes, the dark spots where the nose or elbows poke out from people stuck in various poses underneath the carpet of alien flesh, very obviously being fed upon.

I was so outraged by sheer incompetence of the media for not noticing something this obvious that I halfway woke up, thinking about how to better spread the information or give an early warning system for a rapidly spreading alien biomass across the surface of the planet. I had a very simple solution; we'll go with the types of media we already know. As such, this is a 3 step warning system; the alien biomass is defined by whichever it is most similar to; Blob, Creep, or The Thing.

3) Blob
If the biomass falls under blob rules, then it can open up or is heavily acidic, meaning anyone who touches it can be broken down or melted into its mass. This is the least dangerous of the three despite still being incredibly dangerous. In this case, simple containment measures like extreme heat or cold, fire, chemicals, or whatever else could be used to try and keep it contained.

2) Creep
Like Starcraft's Zerg creep, the goop hive stuff Xenomorphs use from aliens, or that one SCP, this biomass version is living tissue that supports other structures or alien encouragement. This one could still open up or absorb people who touch it, but it's differentiated because now it can also support other structures or creatures; such as spawning tentacles to attack low flying aircraft or creating short lived creatures who can expand its influence or go capture humans to add to its biomass collective. It may also be a part of a natural alien ecosystem or be a tool for terraformation, causing more damage to the natural world in addition to just eating everything it touches.

1) The Thing
Obviously, if we're going by the Thing Rules, then this is the worst and most dangerous one. Thing rules are similar to Creep biomass, able to create new living things or morph itself, but with the addition of being universal across all living things and is able to create its own life forms or split into pieces that are long lived and not reliant on the creep's biomass to sustain its life functions. If the alien biomass follows Thing rules, then all bets are off. It might be able to take over biological things it touches, copy life forms, roll up into a ball and become a giant monster, split its pieces apart, etc. Obviously if this was actually unleashed anywhere on Earth it is highly likely it would just destroy the whole world and assimilate anything without anyone able to do anything anyway, which is why it's the highest on the warning system, you're totally fucked on this level, but at least you have something a little more accurate.
