Where are the easter eggs located in Monaco?

Question

I came accross two or maybe three of the game's easter egg, playing the Mole and digging in some maps' regions.

Are there others? Are there other ways to find easter eggs than digging? Where are they located?

Answer 1

Here are the lists of all the text easter eggs I can find by digging as the Mole in the standard levels. As of Dec. 14, 2013, almost all of these can be found by browsing though the Steam Community Screenshots (exceptions start with an asterisk).

Addendum: They just released the Enhanced levels on December 15th. I have yet to check how many of these easter eggs are still intact. Will post when I do.

The credits have some extra lines:

"Monaco is an online multiplayer game. You may encounter some people online that are difficult to describe as anything but nut-punchers. Please treat others online the way you would like to be treated in person. Even the nut-punchers."

If u go up to the toilet, you will start using it, unless you are the redhead, and if you do this long enough, the toilet will flush when you stop.

Answer 3

There are lots of other easter eggs. Other than the occasional easter egg, there is no other way to find them other then by digging.

Simply by browsing through Monaco's steam community screenshots section, you can find screenshots of other esater eggs, but there is no list of them at this moment.
