Harold's Laboratory is the workshop of the scientist Harold Lillja in the Turtles' dimension.


Harold Lillja, Donatello, and April O'Neil built a functional Interspatial Teleportation Unit in Harold's laboratory. Donatello wanted to perform a worthy field test and gathered his brothers and Casey Jones. The Turtles, Casey, and April would teleport to The Lair and surprise Splinter. However, Harold was irritated with a fly and accidentally hit the spatial dimension switch and they were transported to a parallel dimension.
