A promotion for the offer, which can only be redeemed on Valentine's Day, has appeared on YouTube.
The adult toys on offer include a pink frilly blindfold, a black feather tickler and a head massager.
Before you and your partner rush out for a saucy Whopper, though, the promotion is only available in Israel.
It's a campaign that seems to be aimed at people who forgot to book a candelit dinner for two.
"Kids meal? That's for kids," the advert's narrator says.
"Burger King presents the adult meal, with an adult's toy inside."
