I'm still going with bored, lonely child playing with dolls for friends. I'm glad it's given you your sister. It's both given and taken and given and taken some of family so, not to be a pessimist, enjoy it while you can. Just in case. In terms of the "villains" thing, maybe it was an older or younger sibling being jealous. They didn't want to share their toys so they decided to ruin the fun.
