As you saw in the description, Pokemon contests are meant only for coordinators. Your job as a coordinator is to earn the five ribbons of each section. There are three sections. Just shortly, I'll explain each one with a brief description.
Beauty Contest- This is the most participated subject in most contests. The beauty contests focus on how beautiful, you, your Pokemon, and most especially your Pokemon's moves. Eating things such as dry poffins can raise your Pokemon's beauty.
Tough Contest- As the title says, these contest focus particularly on how tough your Pokemon look. So just a reminder, don’t go to a tough contest entering a Cleffa. Eating sour poffins can raise your Pokemon’s toughness.
Smart Contest- Your Pokemon must look simply intelligent, which means that it must be well-mannered and it has to be able to sit up straight. Smart moves include moves such as Nasty Plot and Confusion. Eating bitter poffins can increase the intelligence of your Pokemon.
Cute Contest- Being cute takes a lot of effort. You must be able to tell the difference between cute things and beautiful things (Ex. Jigglypuff vs Milotic). You also shouldn’t get your hopes up if you enter a Pokemon such as Slaking and lose. Eat sweet poffins and your Pokemon will be cute in no time!
Cool Contest- Pokemon such as Snivy and Treecko don’t have to take much effort to be cool. It is hard for most Pokemon to stay cool in front of a lot of people, and it will take time to practice on. Moves that appear cool such as Thunderbolt will appeal the people who judge. Eating spicy poffins can enhance your Pokemon’s coolness.
So you kind of got the idea of how contests work? Well if you want to enter one, fill this out on the time of a contest.
Name: (full name of character, please)
Age: (age of character)
Gender: (male of female)
Pokemon and Points : (The Pokemon that you will be entering and the number of points they’ve earned. If a Pokemon eats a Dry Poffin, they will earn 1 beauty point. If that same Pokemon eats a spicy poffin, then it will have 1 Beauty and Cool point.)
Contest: (what section are you entering? Ex. Smart)
Contest Level: (Normal rank, Intermediate Rank, Ultra Rank, Specil Rank, or Master's Rank. If you've won the Normal Rank, you go to intermediate. If you've won the Intermediate Rank, you go to the Ultra rank and so on.)
You will be automatically approved on the day of the contest if you’re a coordinator.
