McDonald's SpongeBob-One Piece Happy Meal Launches September 15

McDonald's is introducing a SpongeBob SquarePants, One Piece Happy Meal in the US, featuring 15 different toys. The crossover campaign comes after a decline in quarterly U.S. guest counts.

The meal will be offered at select locations throughout the U.S., starting September 15. McDonald's has not released a nationwide price for the meal, but customers can collect from 15 different character mashups, including SpongeBob as Luffy and Squidward as Sanji.

McDonald's last month introduced the Hello Kitty, Godzilla meal with eight toys on August 18, which also encouraged repeat visits. The new line follows this trend, featuring 15 unique designs to boost sales.
