I'd question your sourcing, Love Robin; doing a little research, Snips and Snails weren't mindwashed by Midnight Sparkle at any point. They were transformed into demons by the demonic form of Sunset in the first movie, and quite clearly retain their free will ("This is gonna be so cool!") and willingly go along with her plan after their transformation

So, long and short, they can stay. Zorpox can be cut, I think; Midnight I'm neutral on.
