Upon reaching the top, they encounter the Broodals, who were hired by Bowser as his wedding planners. While exploring the tower, Mario captures a frog, first learning of this being Cappy's main ability. Cappy informs Mario that they may be able to find a usable airship in the next kingdom, accessible from the Top-Hat Tower.
Mario and Cappy decide to team up to stop Bowser's plans and save both Peach and Tiara, and using the piece he collected, Cappy transforms into Mario's cap, allowing Mario to use his abilities. Upon being calmed down, Cappy introduces himself and explains to Mario that Bowser not only had attacked their kingdom, destroying its airship armada, but had also kidnapped Tiara, Cappy's sister, to use her as Peach's wedding headdress. Mario wakes up, startling Cappy, who attempts to flee. Cappy begins nudging Mario to awaken him.
