"Stallia: Decent staller, although doesn't immobilize zombies or stack with frost"

Objection!

While I was wrong about Sap-fling stacking with frost, I am CERTAIN Stallia does. I've used it myself in Winter Melon strategies, and zombies which are just hit by Stallia move twice as fast as  zombies of the same speed hit by both Stallia and Winter Melon. I'm certain of it this time!
