I've drawn some more Rainbow Friends as Skibidi Toilet characters.

Yellow as Buzzsaw Mutant Skibidi Toilet.

Cyan with G-Toilet's Smile and mechanical arms.

Story explanation:

Cyan is injured due to the finale of Chapter 2 (The fall and by crashing through the debris).

And finally, Red as the Unfinished Mutant ST. (The Red refered to here is the unused looky one from the Chapter 2 game files, not the Scientist)

Story explanation:

Created by fusing a human body with mechanicle parts and the Red Looky. He was a failed prototype made by the Scientist.
