You will only need to find one of the three Easter Eggs in order to receive the award at the end of the game.

In the antiquities tent, grab the pick from the right table.



On the shelf along the back wall, there is a vase featuring a bunny and an egg. Use the pick on the vase.



The vase will shatter, revealing an egg inside.

NOTE: You must do this prior to solving the scarab puzzle but after discovering the missing scarab.

Reposition the scarabs on the scarab panel so that there is one scarab in each of the four corners.

Once you do this, a panel will open, revealing an egg!

Before you solve the scale puzzle inside the cat tomb, place one of the other two easter eggs into the slot.



When you do this, you will receive the old egg you inserted back, and a brand new egg will emerge from the slot!
