Hungry Big Fat Simulator

Explore a massive metropolis and evolve into an enormous twin boss character.

This hilarious character will gain an extraordinary amount of weight to transform into a colossal goliath in the yellow sibling jumper game. Capable of devastating the terrain, this figure becomes the most massive entity in the universe through surprising rainbow-themed challenges, creating optical illusions to manipulate scenarios. The city streets overflow with tempting fast food items like burgers, chicken sandwiches, and pastries in the Ragdoll hometown of these mischievous rainbow companions. While maternal figures tend to infants in nurturing minigames, this insatiably hungry giant proves extremely cunning in the clever food-based legend adventure.

Move through fully destructible surroundings while carefully evading potential dangers. Use accumulated grease currency to unlock special abilities and wield unique powers to wreak havoc on everything surrounding you!

Your size directly correlates with consumption - devour burgers, doughnuts, and even bystanders! This is the world of Fat Twin Sibling!

Sibling rivals compete fiercely to achieve maximum obesity. Consume every edible item in sight to claim the title of most massive siblings.
