Possibly me is the sussiest of imposters.

(I'll get to the Sweetie Giraffe related ones later I don't have time for drawing rn)

Imposter #1 looked at imposter #2. Imposter #3 blinked slowly because his (her? their? its???) eyes were inconveniently glued shut with honey.

Imposter #4 stabbed imposter #3. Imposter #3 tried to stab imposter #4 in response but stabbed imposter #1 while they weren't looking, and so imposter #1 stabbed imposter #2 thinking they were the one that stabbed them, and imposter #2 fell over and stabbed imposter #4 on accident while getting stabbed.

Twilight Sparkle facehoofed at the most catastrophic social experiment she'd ever run.
