Exclusive item

Trade Items are a certain kind of item the player can collect in Pokémon Mystery Dungeon 2. When in the treasure bag, they help party Pokémon in different ways. Every different Pokémon and Pokémon type has a set of items that can affect them. For example, the Cynda-Hair boosts the special defense of Cyndaquil, and the Poison Dust boosts the attack and special attack of Poison Pokémon.

If two or more compatible trade items are brought to Croagunk at the Guild, he can trade them in for a rarer trade item. For example, if the player has the Bulba-Fang and the Bulba-Claw, which are both 1-star rare trade items for Bulbasaur, Croagunk will trade them in for a Grass Guard, Bulbasaur's 2-star rare item.

If a Bulba-Fang, Bulba-Claw, and Grass Guard are brought to Croagunk, he will trade them in for the very rare Leafy Tie, Bulbasaur's 3-star rare item. Each legendary Pokémon has their own 3-star item as well, which can be found in locked doors in dungeons.

Trade items are usually found in treasure chests taken from defeated enemies, which are then opened by Xatu.
