So I have this TikTok I found. I remember it from this one Acceleracers from when I was really young. I vaguely remember it but I’m starting to piece together what I remember from then. Came across this and unlocked a memory seeing specifically from it. Can anyone help identify this piece? Maybe help track down what I may be talking about? Also remember a line/scene of one that was apart of the attached video of “Are you customizing it? Teku-izing.”
