I AM FLY

Hungry/Big Eater/Fatty/Mutant achievements require you to collect 20/100/300/1000 red poops without dying!

It will cost you more than an hour and requires a very strong patince. Bottom right corner is your safe zone. If you die during the progress, it is gone for good, you have to restart! In game's current condition, you can not even pause the game but you may go AFK at the bottom right corner when you are tired.

Avoiding tail won't be enough, sometimes the cow will be spraying... erm... you know what it is... You have to avoid it as well. After a while it will permanently stop using this "skill" so grind will be relatively easier. For being super safe, only move when tail swings to leftern side. Focus on collecting Reds and Purples will give you immunity for a short while. Don't be greedy and it is just a matter of time to get 1000.
