Lings and acid

[Wrazzy]

there should be some kind of secret ling signal you can turn on/off

Like if you're a ling you can hit a button and with it turned on all other lings who examine you get a "you detect changeling pheromones coming from Steve Butts"

Whether they decide to respond in kind and work with you or murder you and eat you for sweet, sweet DNA is up to them, but if you want to take a chance and turn it on you can.

I was thinking of that. An option to put out some sweet pheromones alerting other lings of your presence, can get you a buddy but will probably get you eaten.
