how do I finish ep.3 (what digs beneath)?

*Investigate where all the rats are coming from.

First of all though, head to Frankie's house and search the chimney. You will find the Microfiche so give it to Jimmy, thats is your hidden want complete. While we are sidetracking, we might as well get the errand out of the way. Go east from the main town as talk to Jebediah. He wants you to give a luxury chair to Mrs Hogg. She is normally at the power plant so find her and give it to her. That is the errand done for this episode.

Now, back to the main quest. Head north of the town and go west to enter the salt mines. After you talk to Lord Mole, you will be encountering Penelope Redd and she will ask you about the moles and she thinks that they are going to make some suicidal weapon of mass destruction.

*Pluck the spines of a flowering Spiny Cactus
*Acquire a chuck of fissionable plutoium
*Find a pair of rubber waders
*Get a pile of scrap iron

Anyway, head to the workshop north of you and talk to Optimum Alfred and you will start to play Chop Shop. After that, you realise that you are not strong enough to get the iron so you have to get Jimmy.

*Find someone strong to help rip out the iron

Be friendly to Jimmy and he will follow you to the factory and help you rip out the iron. Now we have the iron. Head to the pawn shop and buy those gloves for 450 Simoleons. You will need it to pluck needles. Head south from your house and go to a cactus. Pluck those needles. That is another one completed.

Head to the Casino. Talk to Luthor and for a small price of 300 Simoleons, you will recieve a chuck of plutoium in the mail. Is that safe? While you are there, talk to Pepper Pete and he will tell you where you can find some waders that he lost.

*Dig Up the waders in the field behind the factory.
*Pick up the plutoium behind the City Hall.

To get the second objective, go to the mail and pick up the note. Then head to city hall, go behind it, near the tunnel and go pick up the plutoium. Now for the waders. Go behind the factory, via the right hand side and dig the patch of sand. Now you have the waders and the final objective

*Return to Lord Mole with all of the items

Simple. Go to the mole and give him the items. Make sure that your aspiration meter is full, the hidden want and errand complete for the full ratings. You will go to a commerical break before you enter. After you enter, you will face a showdown with Penelope or the Mole. Choose what team you will side for.

Choose who to side with by talking to Penelope Redd or Lord Mole

Choose who you want and you will play a strange human mole whacking game. If you sided with the mole, have to hit the humans, and vice versa. The result of it will end the episode.
