One of the hardest final bosses, besides Cackletta in Superstar Saga. Spent ages trying to beat up Elder Shroob. Kind of a dark story. Before I knew how to grind, Toad Town's enemies and Shroob Castle legit terrified me with how tough the enemies are. Atmosphere was great, favorite part was seeing Bowser and Bowser Jr. work together - that whole Thwomp Volcano bit is great.
