Ducks

Ducks is a former shareware, now freeware Lemmings clone for DOS. Instead of clearing the path to a portal for green creatures, the player controls a green duck, the leader of oranges ducks that must be guided to a rocket ship. Clicking and holding the right mouse button on any place of the gamefield makes the leader move towards it. When the green duck is close enough to the orange ducks, they start to follow it. Moving the mouse while holding down the button makes the green duck change direction accordingly. The rocket ship has a number on top, indicating the number of ducks necessary for it to take off.
