The Teenage Mutant Ninja Turtles have helped the Mall of America set a new world record.

The mall teamed up with Nickelodeon to break the Guinness World Record for the largest gathering of Ninja Turtles.

A representative from Guiness confirmed there were 836 Ninja Turtles there, more than the previous record of 786.

This was held to celebrate the grand opening of the mall's new ride, Teenage Mutant Ninja Turtles Shell Shock.
