Heart

Hearts are found (usually hidden) in many places throughout the games.

In Croc: Legend of the Gobbos
Picking up a heart gives Croc an extra life. The most common places that Hearts are found are usually in Bonus Areas, which are usually in secret places by picking up Sparkling Stars or landing on special Platforms. Every time Croc is hurt during the game while holding no white crystals, he loses a life and returns to the start of the level or at the beginning of part of level, for example, when Croc enters a door. Hearts are found in Smash Boxes, lying around, and are also obtained by collecting 100 or more white crystals in a level. Croc starts a new game with two lives, and when he dies while the count is 0, the game is over and Croc must restart the level he last played.

In Croc 2
Hearts are now used to monitor Croc's health. Croc will start the game with 3 hearts, and collecting a Heart Pot will extend the number of hearts that Croc has. Once Croc gets hit with 0 hearts left, the game over screen will play.

Trivia

 * The maximum lives Croc may have at one time is 98. If he touches another one, the animation will play but he will still have 98 lives.
