Playmates Toys has unveiled its all-new 2015 Teenage Mutant Ninja Turtles line, at New York Toy Fair, inspired by season four of the Nickelodeon TV series.

"After five years of an incredible partnership, we are excited to be working with Playmates Toys on what is now the most sought-after toy property, the Teenage Mutant Ninja Turtles," says Manuel Torres, senior vice president, global toys and publishing, Nickelodeon Consumer Products. "The new toy segments we're launching will elevate the Turtles' popularity even more to fans around the world."

The toy company is planning its biggest expansion in the line to-date with a new range line called Mutations that allows kids to mix and match pieces from both villain and hero figures, extensions to the Half Shell Heroes preschool line and a new die-cast segment called T-Machines, in addition to new action figures, vehicles, role play and play sets.

"As the Turtles continue to be one of the hottest brands, we're excited to introduce toy segments that bring all-new levels of play to the Turtles world," says Karl Aaronian, senior vice president of marketing, Playmates Toys. "For example, kids will now be able to recreate the Turtles' mutation, transform an action figure into a play set, or roll through the sewers and streets with the new die-cast vehicle collection."
