"The Rusty Twins live at the Rubbish Dump in Gigantic Paradise, scrounging for food. They are poor and hungry and will trade bones and canned food for some of the better items people throw out at the Rubbish Dump.
The Rusty Twins need your help. They have 30 different missions for you, each harder than the last. You w
ill need to find bones or canned food and bring them back to them. If you fail to bring any of them, you will have to start again."
The Rubbish Dump is a mission in which, by completing thirty levels, you can obtain a Rusty Potion. It's located in Gigantic Paradise right next to the Leprechaun. Levels 1-15 are easy as they require 2-3 Bones, while levels 16-25 are at medium difficulty as they require 3 canned foods, and levels 26-30 are hard as they require food from the Restaurant. The mission image is shown as two Rusties with one colored orange and one colored yellow, and they are brothers. At level 24, the prize is a Glass Costume. You can visit the Rubbish Dump Mission here.
