Which studio created the 1990 film Teenage Mutant Ninja Turtles’ creature effects?

Jim Henson’s Creature Shop created the creature effects and turtle costumes for the 1990 film Teenage Mutant Ninja Turtles.

The Creature Shop, founded by puppeteer Jim Henson, built the complex animatronic suits that allowed performers to portray the four turtles with moving eyes, mouths, and facial expressions. The work was a major practical-effects achievement for a superhero-style film made before modern digital character animation became common.

The costumes required performers inside the bodies while operators controlled facial mechanisms remotely. This combination gave the turtles a physical presence while preserving the expressive qualities associated with Henson’s creature work.

The film’s effects are sometimes attributed generally to “the studio” or confused with Industrial Light & Magic, which handled visual effects on many other large productions. For the 1990 Turtle movie, the distinctive hero suits are specifically linked to Jim Henson’s Creature Shop.
