"Sophie, I want to but..."
"Dale, but what?"
Sophie was barely able to Dale in her peripherals, shocking her to witness he was also copying the mimic's every movement like she was. Unfortunately for the both of them, Dale had been subconsciously following their movements, albeit only in the same general direction, but it was enough for the mimic to ensnare him as well, completing the pair.
This clearly pleased the mimic as his smile simply widened in excitement as it wasn't common for mimics to ensnare multiple people, let alone encounter them. That's when he decided to have a little fun with them before changing them.
First, he made sure the two still made eye contact with his own large eyes keeping them trapped in his mimicry. Then he started to move around wildly while sidestepping in a circular motion, causing the two to follow in his uncoordinated dance. Then he had them play with each other's hair, running their hands through each other's as well as his own fur.
All the while, Sophie and Dale could only helpless follow the mimic's movements, their pleads going unnoticed or ignored, to the point where the two had given up on trying to escaped and just hoped that they would be able to get out of this situation as soon as possible. Oddly enough, the couple did realize that they were not getting anymore fatigued or worn despite all the sporadic and tiring motions their captor was forcing them to follow.
Eventually, the mimic had its fun and stopped in front of the couple to decide what to do with them...
