The way I saw it, the mother is also heavily pregnant again, the gumball machine globe decoration over her baby bump.That slot and coin, and then the gumball comes out. It's a direct reference to having sex, probably not suitable for explaining the joke to young children. If your church had one of those Halloween parties as an alternative to going out trick or treating, you probably wouldn't wear this costume for the party.
Among other adults, I think it's pretty funny.
