From November 7th, 2017 until December 4th, 2017, participating McDonalds locations will be selling Happy Meals with a Pokémon Toy and TCG card.
A Happy Meal with Pokémon Appeal!
McDonald’s Happy Meals are set to get even happier with Pokémon inside!
Hamburgers (or cheeseburgers…or chicken nuggets) are great, but everybody knows they're even better when you get a cool prize along with them. Good news: Pokémon is teaming up with McDonald's to bring you some fantastic Pokémon toys and Pokémon Trading Card Game cards featuring Pokémon from the Alola region of the Pokémon Sun and Pokémon Moon video games.
Starting November 7, 2017, and running through December 4, 2017, be on the lookout for Happy Meal toys featuring Pikachu, Rowlet, Litten, Popplio, Grubbin, Yungoos, Solgaleo, and Lunala. Hungry Trainers will also get one of 12 Pokémon TCG cards to collect and trade with their friends. So bring your appetite, and get ready to add some great new toys to your collection!
