100 Hidden Cthulhu Fish

100 Hidden Cthulhu Fish is a free, single-player, mouse-controlled, hidden object/observation game.

The game consists of four outline images, into each of which 100 fish-like creatures have been inserted. These creatures are of different sizes; some are just heads while others are curled up, they can be fully in plain sight or partly hidden or a combination of any of these descriptors.

The player can zoom in on an area of the image by rotating the mouse wheel, while right clicking and dragging moves the enlarged picture. Clicking on a creature causes it to be coloured green and reduces the creature counter.
