PS1 Sheep

Sheep is a strategic puzzle video game released for PlayStation, Microsoft Windows and Game Boy Advance. In 2001, it was released for OS X by Feral Interactive.
Sheep bears some resemblance to the video game Lemmings. The player can choose between 4 shepherds, the humans Adam Halfpint, Bo Peep, Motley the dog, and Shep.

The player must lead the 4 sheep through a series of obstacles to the finish line of the level.

There are a number of different worlds, starting with Polygon Farm and others such as Village Fete and Lost in Space. If you collect all the golden sheep trophies in the world, you can play the bonus game.

The obstacles between you and victory vary by world, including tractors, knights, archers and demonic cooks. In the end, you must thwart the plans of the mad scientist Mr. Pear and his cows.
