The Basketball is an item in Pipe Down!. The Mushroom King bought two Basketballs for Princess Peach's ninety-ninth birthday party, although she dribbles away with one of them while possessed by a pair of sneakers, ignoring the other one. Mario and Luigi can find the second Basketball on a set of stairs while Toad leads them to Peach's shoe vault, and Luigi carries it under his arm. It can be used if the two of them reach a chamber with three large pipes while lost in Pipe Land. Luigi gets the idea to throw the Basketball into the pipes to hear what's inside. When he tosses it into the center pipe, it rattles around the pipe for a short while before it reappears from a side entrance, and they decide that it has nothing of interest. Luigi then tosses it into the leftmost pipe, and they hear it get chewed to pieces by some monster, leaving them to conclude that they should take the rightmost pipe.
