MooMoo 

A cow. He was born in the early 1900s or late 1800s and is, as of 2024, in her growing phase. She has ten phases: birth, normal, power, eating, growth, swelling, shrinking, feeding, powerless, and death. MooMoo's feeding phase, which will happen around 2500, will be the end of humanity as we know it as they will all be eaten (luckily we won't be alive). MooMoo is known for her infamous Acts of 1937, where she became famous for her poisoned milk and other atrocious acts.

MooMoo is the best cow.

moomoo.io

The greatest browser game in the history of mankind.

...

Said no one ever

It's essentially foes.io but worse in absolutely every possible way. Yet it makes more money than any game made by Sidney de Vries.

A: Moomoo.io is so good!
B: Really? Then No Man's Sky is the best game of all time

moomoo.io

a game that used to be good, but is now filled with:
Gold buggers (people that use a bug to earn shit-tons of gold)
Scripters (people who download hacks because they suck at the real game)
Toxic kids (you already know these kinds of people)

the game used to be good but now its fucking garbage
not hot garbage just garbage
