Shroob planet

Shroob Planet is the planet where the Shroobs live. It was a monarchy ruled by Princess Shroob and Elder Princess Shroob. This planet is shaped like a purple Mushroom.

In Mario & Luigi: Partners in Time, the Shroobs were looking for a new place to live, as the planet they were living on was withering. During their search for a new home, they spotted the Mushroom Kingdom and inaded soon after. Mario, Luigi, Baby Mario and Baby Luigi then defeated the Shroobs, however.

It is unknown if the Shroob Planet still exists; the prologue for Mario and Luigi: Partners in Time states that the Shroob's planet was dying and withering.
