Pikwin/Pixelmin
From Pikmin Fanon
pixelmin levels are rare bonus stages in Pikwin(Wraith edition) that have a 2d olimar and louie going through a 2d level similar to Hey Pikmin and similar to caves in pikmin 2. the objective is to get to the end of the cave while picking up treasures and enemy corpses along the way, but olimar and louie have limited pikmin and limited health.
