This is a story-based achievement, as such, it cannot be missed.You can unlock this achievement by completing World 1. This is fairly simple and the boss, Tori, is very easy to beat.
In order to defeat it, you must hit the bulge on its head when it pecks the ground or when it's done blowing wind at you.
Once you complete the boss level, this achievement should unlock.
I recommend using
AiAi for this world as he is a well-rounded character that is perfect for this world.
