Definitely An Italian Plumber is an achievement (trophy) in Borderlands 2
You get it by killing Donkey Mong

Killed Donkey Mong No Achievement[edit]
If you did not get the achievement after killing Donkey Mong, it's probably because you killed King Mong instead. Their names are similar, so it's easy to get confused.
