That's what I've been working on, and will be working on for the next 3 to 4 days most likely. Examples you say? Surely.
This one is "Sharkburned Again!", you get it for eating the good Admiral.
"Faster Food", gotta get a 10x combo meal while non-frenzy.
"Feather Sniper", get it with a 3x bird shot combo.
"Man Fisher", knock some poor swimmer onto a fishing hook.
All the originals are 512x512, but these here are the ingame 64x64 versions. Now, just a few screenshots.
Here's the new addition on the title screen.
And this is what the actual achievement screen looks like.
