The fun-loving nostalgia and callbacks – even Vanilla Ice’s ‘Ninja Rap’ from 1991’s dorky Teenage Mutant Ninja Turtles II gets a nod – are all cut with an affecting note of melancholy.

Seth Rogen is among the creatives showing off the unique animation style for the upcoming Teenage Mutant Ninja Turtle: Mutant Mayhem, which Paramount and Nickelodeon Movies will open on Aug. 4.

Over on Reddit, the user UrSain posted a short video that shows their take on Kakashi vs Obito. The artist said they began to do this animation by hand and have already amassed 290 frames.
