For further information, see the Turtlepedia article for Splinter.
Master Splinter was tending to his miniature Zen garden at The Lair when Donatello gathered everyone else for a trial run of the Interspatial Teleportation Unit. Donatello wanted to teleport everyone into the lair and surprise Splinter. However, when Harold Lillja accidentally hit the spatial dimension switch, they teleported briefly to the lair then were displaced to another dimension. Splinter didn't see them and assumed the television was left on again. Caught unaware of the Turtles' return, Splinter praised them for being so stealthy. He was surprised when they, April and Casey hugged him.
- Initially, Splinter was also going to go to the Ghostbusters universe and have a fun conversation with Janine Melnitz but his involvement was edited down for space.
