oops there's a homicidal duolingo bird
This mod introduces a Duolingo bird boss mob into the game. To summon this adversary, you need to craft a Spanish textbook (the crafting recipe can be found in the images tab), then use it to hit a parrot. The boss progresses through three stages, with each subsequent stage becoming significantly more powerful than the previous one. In the screenshots section, you'll find visual examples.
The modification was developed in less than twelve hours, so don't expect too much from it.
