I'm having trouble w/this. I've gotten the Digger Drill from the old guy in Eterna City, but when I go to the Underground & look for the Drill in my traps, it's not there! I've double checked so many times & it's still not there. Help!

Maybe you used it...?

Nope, can't use what I can't find.

have you tried making a base anyway?
i dont think it shows up the first time
i remember checking the traps and it wasnt there
i pressed A on a wall and it made me a base

go up to a wall and press A, if that doesnt work, then go back to the guy in eterna, if that doesnt work, ur game is glitched

He gives you a list of things to do, one at a time. Each time you have to return to the surface, later on he'll give you your Digger Drill. Your game isn't glitched, you just haven't progressed far enough yet.

He said he got the drill already. Anyway, if you go down infront of the Pokecenter is Solaceon there is a merchant who will sell you another digger drill (if yours is **** or something).

Actually, I think any Trap Hiker can sell you one, for a sphere around size 15-20(I think the type varies). There are 2 trap merchants in the largest area of the Underground (the area you get to from Eterna), one of them under Solaceon as Original said.

You get the Explorer Kit from the man in Eterna City.
It's what lets you go underground.

You get a Digger Drill from the guys underground while you are already underground.
That's how you make a Secret Base.

I thought that the Underground Man in Eterna gives you one to start off with, but if you can't find it then they're for sale cheap in the underground.

You do get one after you complete a few tasks for the Underground Man. You can also buy one from Trap Hikers for varying kinds of spheres size 16-18.
