Here's how the Biskit's twins defeat goes in Thomas and Twilight Sparkle's Adventures of Littlest Pet Shop: Blythe's Big Adventure.
Whittany: Okay, Brittany. Let's do it!
Brittany: This will teach Blythe to say "no" to us!
Russell: Oh no! (rolls up into a ball) (makes noises)
Brittany: Aah! A porcupine! (scream; back up, only to fall off the catwalk)
Russell: (grabs buckets tied to Biskit twins with ropes; tone is angry) I'm a hedgehog!
Brittany and Whittany: (screaming; open their eyes, realizing they're only hanging a short distance above the stage and have made idiots of themselves in front of a live audience)
Brittany: Uh. Like, phew.
Whittany: Yeah! That was a close one.
Russell: (lets go of buckets, causing contents to spill all over Biskit twins)
Brittany and Whittany: (scream; run away, clearly humiliated)
(Dogs bark, then begin to chase the twins)
