There's another kissing foe in this game. ((Also, the 2nd kiss in the original article is unrelated to the game.))
Starkisses are enemies that blow kisses to attack. They make little flashing hearts float at Mario or Luigi by air kissing. They're not really all too dangerous, but when you're in a bad situation... The vid I'm supplying has multiple instances of them.

Starkisses aren't a big threat. Their attacks are pretty easy to dodge, especially when you don't need one brother to carry the other. They tend to be defeated easily. They do have the strange factor of being healed by lightning... And one last note, they can be jumped on just fine.
