Twisted Sister / Cover Up - S2-E11
Question: After Buttercup loses her blanket a monster attacks Townsville, and Buttercup doesn't have the confidence to defeat it until Blossom goes to the house, comes back with her blanket, and gives it to her. Buttercup gets her confidence back and defeats the monster. But later Blossom tells Buttercup it's not her real blanket. It's just a fake blanket she found to get her through the fight. How would Blossom know if it was Buttercup's real blanket or not? It looks exactly like the real blanket.
Answer: It depends on where Blossom found the new blanket. For example, if she found the blanket for sale brand new in a store, she would know it wasn't Buttercup's real blanket.
