Capsules are collectible items on the boards that appear in Mario Party 5. The capsules replace the item system that appears in the previous Mario Party installments. A character can receive a capsule through a special dispenser that appears on all the board maps in Mario Party 5. The capsules usually contain objects and characters that appear in other Mario series games, which allows more Mario characters to make cameos in the Mario Party series.
When a character possess a capsule, he/she have an option of either using the capsule on themselves or throwing the capsule on the board up to ten spaces in front of them. Most of the capsules have a fee that a character must pay in order to receive its effects. If a character decides to use the capsule on themselves they will then be required to pay a fee for the capsule's effects. If a character decides to throw the capsule on the board, it will then create a trap that any character can land on. When a character throws the capsule on the board, the capsule will leave a symbol on that particular space. The capsules are only allowed to be thrown on blue and Red Spaces. A character can also throw a capsule onto a space with an existing capsule icon to replace it with their own. If a character lands on a space that contains a capsule symbol, they will be subjected to the effect of that capsule. The capsules are divided into four categories that are grouped by color: event, coin, capsule, and special.
