possible. Certain stages also contain boss enemies known as "Guardians" that Croc must defeat in order to progress to the next stage. Various different collectibles are scattered throughout stages, including small, gray crystal orbs that act as Croc's health, and red hearts that give the player an extra life when collected. Also hidden across each stage are 6 Gobbos being held captive by the Dantini tribe that act as Croc's main objective throughout the length of the game. 5 of these Gobbos are hidden in various locations throughout the level, often collected by solving a puzzle or completing a challenge, whilst the 6th Gobbo is located in a bonus room hidden behind a set of doors that can only be reached by collecting 5 colored crystals hidden throughout the level. Rescuing every Gobbo before a boss level in each world unlocks a secret level that can be completed in order to collect a jigsaw puzzle piece. Subsequently, collecting every puzzle piece in the game unlocks an extra island containing more levels for the player to progress through. While collecting the Gobbos is not mandatory to completing the game, doing so is nonetheless necessary in order to face off against the game's final boss and unlock the game's true ending. Croc's maneuvering abilities are somewhat comparable to that of Mario's in Super Mario 64, with his primary methods of movement consisting of the abilities to run, jump, climb, and swim using either the analog stick or the D-pad, as well as touting the abilities to perform a sidestep and a 180-degree quick turn as other methods of maneuver. Croc's main method of attack consists of a full-circle tail swipe that is used to defeat enemies and bosses, as well as a hip drop move that can be used to break open crates containing collectibles. Croc's in-game health is represented by the crystals that the player collects throughout the game; when Croc is hurt by an enemy, all of his crystals are lost and scattered around him in several directions (similar to a mechanic commonly used in Sonic the Hedgehog games). If Croc is hurt while he has no crystals, the player loses a life and is sent back to the beginning of the segment of the level they are currently in.
