Visible crew/equipment: After the intro, when Garvin tells Gia to go home, Data is standing on the stairs and the actor's green mark is somewhat visible at Data's feet. This green T-mark is clearer when Data hands Garvin the radioactive box he's carrying. Then, when Garvin walks over to the table, there's an orange T-mark on the ground. (00:04:55 - 00:07:40)

Other mistake: After Shredder transports Bebop and Rocksteady back to his lair, he joins them on the transporter platform. Shredder then demands to know the exact location of the TMNT hiding place.

Continuity mistake: At the end, when Teddy and his friends get the directions to the Wizard's fortress, Prince Arin's hair is bright yellow as he shakes Wooly's hand. In the next shot it's back to his normal orange hair.
