Hidden blocks are scattered throughout the game world, often containing coins, items, or even badges. Many are invisible until Mario jumps directly beneath them. Pay attention to suspicious-looking empty spaces or patterns in the environment. Goombella's Tattle ability can sometimes hint at their presence. Later, Flurrie's Gale Force can reveal hidden passages or items. Always jump in every suspicious spot, especially in new areas. Some key items for side quests are also cleverly hidden, requiring keen observation and partner abilities to uncover.
