The Lyfe of a fesh is a difficult one indeed but for the most part of your lyfe you say blub the whole time but we will get on to that later lets begin first what you must do to become a fesh:
1-Wear the brightest and yellowest pants and shirt
2-Wear the most fabulous blue shoes and hat
3-Go to a lake and catch a pufferfish (P.S If you spawn it in and not catch it you would be considered a "Fake")
4-Jump into the lake and while your drowning eat the pufferfish
5-Let yourself die to the fesh gawds by drowning
6-Respawn
If you go through these steps you will be able to become the fesh you always wanted to be
Now as a fesh you are able to do many wonderous things like:
-Brag about how cool being a fesh is
-Say blub 24/7
-And many more... not really...
And there you have it the lyfe of a fesh oh and forgot if you want to revert back to a normal human (I dont know why you would ever do that):
1-Slap a pig in the face 3 times
2-Ride him of a cliff
3-Die with him
4-Respawn
This is the complete guide of how to turn into a fesh and back hope it help
