Collectibles are objects scattered in various zones of Club Penguin Island. Players can collect them and exchange various amounts of one type for coins at The Exchange at the Beacon Boardwalk. Some can simply be obtained by walking near them, others require that the player interacts with an object. Every collectible the player collects will have a cooldown time before it respawns and can be collected again. Additionally, gathering various collectibles are sometimes objectives of daily quests.
There is no limit to how many of each type of collectible players can hold at a time, and likewise no limit on how many coins are received from trading them in. Although the counter that shows how many coins are received after exchanging collectibles in The Exchange does not go beyond three digits (999), if a player trades in enough collectibles to yield over 1000 coins, they will receive the correct amount, despite The Exchange erroneously displaying that they received 999.

According to loading screen messages, collectibles that are traded in are used for island projects; confetti flowers are harvested to make confetti, seashells are used for concrete and jewelry, and glowsticks come from neon crystals.
Although there are multiple colors of single crystals, they are counted as the same, and do not have a different coin exchange rate or between them.
