Download Shriek of the Living Dead
In the Shriek of the Living Dead you will have to help the Easter bunny in a special task that he has, but it will not be as easy as you might expect. The bunny has to collect Easter eggs that are scattered around but there are a lot of zombies swarming in the area and you will have to control Shriek so the bunny does not meet with the zombies.
Shriek will take care of the zombies if you simply click on them, allowing the Easter bunny to collect the eggs. The game is pretty simple and it has nice graphics, so you might want to show it to a child, too.
