McDonald's is kicking off a new FIFA World Cup Squishmallows Happy Meal on June 9th, and collectors may want to get ready. The US collection is expected to include 23 different Squishmallows characters to collect.

With the last Squishmallows Happy Meal becoming one of McDonald's most popular toy promotions, these could be tough to find once fans start hunting for the full set.

Would you try to collect all 23?
