Starkisses are found within the Oho Ocean Seabed and above the Gwarhar Lagoon. When they approach Mario and Luigi, they blow love hearts at them. They fight alongside with Malibuts. During the battle, they attack by blowing a kiss with their hints in the battle. The heart travels slowly in a wavy line, Mario or Luigi is unlikely to be poisoned if they take the damage or they take minimal damage to it.
The Starkiss folds its arms when it is targeting Luigi and does not fold its arms when it is aiming at Mario. Mario and Luigi can dodge it by jumping over it, even if they stomp on the heart.
