You have to find the bodies that disappeared during the meteor attack. And you must find out what happened.
Looking at the sign behind the stupid game you notice there’s a piece busted. Use the sign to get the long SIGN PIECE. Walk further to the left and look at the wiener stand. On top there’s a door but when you want to open it, it’s stuck. Use the sign piece on it to wedge it open. You can take the FOOTLONG out.
Look at the wheel of the stand. One of spokes is loose. Use the wheel to get the SPOKE. Use the spoke on the tire and you manage to pry the TUBE out. Walk further to the left and talk to the farmer. He’s not much of a help.
Look at the counter and note beside the huge gap behind it also the hook. Use the tube on the counter to hook it and you’ll bungee down.
Use the tent left of the entrance to find a STRING and a spade BLADE. Use the spoke on the blade and then the string on the blade. You have a full SPADE now. On the right of the mosaic is a dirt floor. Use the spade on the dirt floor to dig a big hole.
Take the moldy brat from your inventory and throw it in the hole. Not knowing the consequenses you unravel the whole story.
