The Embalmment Jar is treasure that can be obtained in Sly Cooper: Age of Thieves in the episode Rob Like an Egyptian. It is worth 247 coins and the time needed to get to the safehouse in time is twenty seconds.
"Whenever someone dies in Ancient Egypt, the dead go through the process of mummification. The jar's purpose is to house the organs removed by those working on the bodies. Thankfully, this valuable jar lacks sort of organs to speak of, as Murray is sure to upchuck if he saw any of them."
It is located south of the Temple of Anubis. Murray must chuck an item at a switch to open the gate leading to this treasure.
