About this project
What does Underworld penguin add?
A new monster, the Underworld Penguin Boss, has been added and can be found throughout the Underworld. Defeating him will reward you with a penguin horn, which you can use to craft a powerful shield resistant to lava, carbide blasts, and dynamite. Crafting instructions are shown in the images. All you need are three diamonds, three red paints, two penguin horns, and a votive shield to transform into your Underworld shield.
