GoAnimate World 3 is the 3rd game in the GoAnimate World series. Another name for this game is GoAnimate World 3: The UTUBETROLLPOLICE come to the GoAnimate World!.
Some remains of buildings are being fixed, thanks to the Element Humanoid attack. A year later, the character cloner is introduced (Which can be used to solve puzzles by stacking or doing actions with them). The cloner factory is bustling with people and GoAnimators equally. Later, the UTUBETROLLPOLICE, finding out about this, steals some of the cloners, not knowing they dropped and left some behind. (The cloners become a gameplay mechanic used to solve puzzles) The UTUBETROLLPOLICE then make clones of themselves, however, due to a glitch in their cloners, their clones are weaker than their real selves. The clone army then attacks the city, will the GoAnimators save the day once more? In the meanwhile, after defeating the Haywire Cloner, they discover that they need to go across the internet from Flash to the UTTP's channel on YouTube, they go there, and eventually defeat Tommy, little do they know that an ally is betraying them (You cannot play as that character and sets the plot for Boss Rush.).
