She is the Great Golden Rrrumba, so of course, the battle consists of her using 3 Rrrumbas to defeat her. so it's another simple boss, But you best watch out when Soccerine tries to move, because it will cause the whole arena to stun you from the earthquake and maybe collapse with falling Rrrumba rocks afterwards! Alternatively, you can use either Elephant Apple or Rhino Mango to attack her without the requirement of Rrrumbas, but it sure requires to bounce on top of a Rrrumba first.
