Hungry Big Fat Simulator

Explore Giant Big City and transform yourself into a huge twin boss.

This entertaining character grows to a massive weight, becoming a goliath in the yellow sibling jumper game. It can obliterate the Earth and become the fattest in the universe across startling rainbow friend games, using deceptions to control the situation. Amazing fast food items like burgers, chicken bread, and treats are everywhere in the Ragdoll Town of Naughty Rainbow Friends: Big Sibling. Mama cares for the infant in the care games, but the fat, hungry giant is too clever in the shrewd legend food game. Navigate around a destructible environment while trying to avoid danger.

Use your oil to purchase power-ups and unleash devastation on everything in your path!

The bigger you get, the more you can eat—burgers, doughnuts, and even people! This is Fat Twin Sibling!

Fat siblings battle it out to get as enormous as possible.

Eat everything you see and become the fattest siblings.
