Support Pokémon are a unique feature of the game. When the item is obtained, it provides a Pokémon boost in both combat and outside of battle. When outside of battle, swim up to the top of the tank and the Pokémon will give you a bonus based on its ability. In battle, it'll give you a small motivation boost. It will be a 5% Jump Power boost the majority of the time, but can provide a 25% Jump Power boost rarely.

Most of the Support Pokémon can be boosted using Candy. Collecting the candy is simple. Every time you beat certain milestones in each league for the first time, you will receive 1 Candy. You'll also receive one when you level up Food or Training to Levels 25, 50, 75 and 100. Finally, after you have reached Trainer Rank 79, every 6,000,000 experience points earned will net you a new Candy piece.
