Is figured to go somewhat along the same route as Love in the Clouds, meaning that all six Pokemon will be have a different set of rules to them.
Green: Must use a green Pokemon. It has to win 2 X contests (Never used smart. If you're drunk, you tend not to be all that smart)
Shamrock: A multi-headed Pokemon. Needs another rule.
Lucky: Luck based moveset (Less than 100 accuracy moves, multi-hit moves, Metronome)
Saint: Requires at least one healing move. Can't evolve.
Alcoholic: All vitamins/drink based healing items goes towards this guy.
Leprechaun: Short. Has to be the last one caught. Once caught, must be holding nugget at all times.
