Wave Translator

Wave Translator is a Etc quest started by Dr. Kim.

Requirements

Offer: Have you gone to see an Alien Gray?...Oh? I guess you haven't gotten much out of it. Of course, not. The Grays are way too intelligent to reveal their weaknesses. Shall we go with option number 2 then?
I have found through extensive research that the Grays converse by sending ultrasonic waves from their tentacles. Unlike talking with their mouths, only truths are told through the waves. You will abe able to get to the bottom of this if you direct the conversation in the right way using the waves, and encourage them to respond to your question.
Of course, you can't just decode the waves. I'm still in the beginning stages of my research, so I need a number of materials to build a Wave Translator. Won't you find me the materials so I can build a Wave Translator?
In progress: It seems you haven't found all the materials necessary to build a Wave Translator. Did you forget what I've asked you to bring? I need 30 Small Spaceship, 30 Receiving Apparatus, 1 Chief Gray's Sign... And 10 Gray's Tentacles. Don't forget!
Completion: Oh, you've brought all the materials I need. Give me a few moments. I will build you a Wave Translator.
(...Bang! Bang! Bang!)
(...Cling! Cling! Cling!)
