Episode: Cozy becomes empress of the parasprites. Everyone is relieved because now she has her hooves full and they don't have to deal with her bullshit.
Following episode: They completely underestimated Cozy's ability to organize even a simple creature as a parasprite which Cozy now has turned into an obedient army that threatens Ponyville. It all ends with Pinkie playing music for the parasprites while Cozy shouts at Pinkie on the top of her lungs to stop playing.
