The difference between day and night is in how the balloon pops. Bubbles come out of the balloon at daytime, and Stars come out of the balloon at nighttime.
The introduction shows each player inflating their balloon slightly.
Players attempt to inflate their balloons to the point where theirs pops first. The three players work together to pop their balloon by ground-pounding their pumps by pressing mid-jump, while the single player tries to pop their own balloon by repeatedly pressing to hammer on their pump.
