This kid-friendly on-rails "shooter" is all about taking pictures of cartoony underwater creatures. The gamer controls an aspiring underwater photographer who is assisting a professor. You must follow the path laid out by the professor and take pictures of all the creatures that you come across.
The game is single player only. There are 5 levels that take place in a coral reef, a ship graveyard, the deep sea, the "abyss," and an underwater volcano. Each area features 12 creatures to locate and photograph. Your objective is to take pictures that score a "three star" rating. To achieve this rating the animal must be centered, zoomed in to show detail, and displaying its personality. You can elicit a display by throwing a "gizmo" at the creature. The gamer will need to play through each level multiple times because certain creatures only come out at specific times of the day, three play-throughs of a level unlocks a "special" creature, and there are hidden Golden Seashells to discover in each level.
