You encounter it after you catch up with Tails and Knuckles. If she does, Tails Doll commits suicide, leaving its Chaos Emerald and the gem on its head. If she doesn't, Tails Doll appears later on and battles either Cream or the other one that survived. Cream has the option to either leave it behind (which lets her traverse the stage much faster), or take it with her. If someone dies, Tails Doll temporarily deactivates.

He is encountered by Cream in Round 2, who he protects. Tails Doll plays a major role the Spirits Series, in Round 1, he is ordered by Robotnik to take the Chaos Emerald to Azure Lake and to stay away from Sonic, it is presumed he is unable to as the next appearance of Tails Doll depicts it with an eye slashed out, which curses it. However, Tails manages to kick the doll despite being electrocuted, launching the doll into the lava where it sinks and gets burnt. Tails eventually flies up to the doll and tries to snatch the stone, but it activates a green shield that electrocutes Tails. When Tails and Knuckles have once again escaped the worlds that they were sent to by sAnITy, they resume chasing after Tails Doll. Tails notes that the Time Stone is on Tails Doll's head, and tries to ask the doll to give it to them, but it just flies away instead, prompting Tails and Knuckles to chase after it. Tails Doll appears late on in the episode, after Tails and Knuckles escape from the respective worlds that sAnITy sent them to. However, it can't do this in the 'X-Dimension', where there is no time. But because of the virus, the Tails Doll fueled by the Time Stone has a strange goal of 'destroying time'. But once, somehow, a Time Stone appeared near it and it began to mix with the doll, becoming its brain.
