Hehehehe, perfect! Just perfect!

Give me some space, okay?

There! It should be ready, are you ready, too?

Lame. Come back when you're ready to go.

Excellent answer!
This here is a cloaking device loaded with the DNA you got for me. When I push this button, you'll be transformed into a Gray, and then you'll be able to enter the base.

Since this is only a portable version of the device, it won't work for long, maybe like 5 minutes tops? All you have to do with it is find the base entrance. Once you're in, you will need to find your way through whatever is in there, and find out as much as possible about what the Grays are up to. Let me know when you're ready to go!

You're back!! What happened in there?
(You tell Ribley about your base exploration, and the encounter with King Rombot.)

A... robot!? And they said it was a toy? Huh... Nothing in my research showed any indication of that.

(Agent Ribley scratches her head) I'll have to keep investigating. These fragments of Rombot blocks that you carried out after the fight will surely help. Maybe Alien Gray was telling the truth... but I can't be sure of that just yet.
