That's true. What were we using our sticky secretion for again? If we're not using it to climb walls or anything, I'd rather get rid of that myself.

reshape mitochoduits to allow energy to be directed towards either the eyes or the skin for increased light generation. (Aka light bursts like a flash bang to visually impair enemies.

Let's get rid of both secreations, and perhaps Secretion Control...doesn't seem to be doing anything for us thus far..

fine lets keep acid and the glowy and get rid of echolocation. Not like we need two methods for seeing in the dark

I'd rather keep echolocation and rely on eye lasers for light if we really need it. Echolocation gives us a whole different way of seeing that we can fall back on if we are blinded for reasons besides darkness. Or if we need to deal with something without looking at it. Really though, I'd rather keep both and get rid of a secretion until the dweller is gone. Once it's gone, we can always drop bioluminesence.

You know guys, we really need to figure out a way to expand our evolutionary capacity.

Right now we can't even afford a full set of limbs with our organs. There's gotta be a way to finagle our way into more additions.

Maybe some way of making things permanent? Or combining evolutions?

evolve bigger brain

evolve radio transmitter for communication with machines

we can produce visible light so I dont see why not

I say we either ditch the Bio-Luminescence or the Echolocation. I say we should ditch the Echolocation, as glowing in the dark kinda defeats the need for hearing where we are going.

Also, what's this about a Low Profile Nose? I don't recall anything about that.

Uh, yeah, keep echolocation, as that's something we know will be useful for now.

Carve depictions of all of your current evolutions on the wall using your shard. Then, devolve all nonessential evolutions and evolve OPTIMIZED BRAIN. Use brain to determine how to increase evolution slots. Devolve brain enough to evolve required evolutions for the process while still remembering your plan.

When your slots are double the total of all previous evolutions, regain all evolutions and proceed to communicate with PERIL GUARDIAN.
