To unlock the Chrome Dimensions exclusive levels, you must find the Chrome Logo symbols hidden on seven levels in Poached Eggs.
The levels that have the Chrome Logo are:
Level 1-16, Level 1-18, Level 1-20, Level 2-4, Level 2-20, Level 3-7, Level 3-14
On each level, simply zoom the screen out as far as you can and you will be able to see the Chrome Logo.
