The way to the memories

After Splinter's death, turtles were depressed. Their negative emotions led them to the strange world. There, one turtle girl called Venus says them to work at master Nayichu. While working, they also meets other turtles, Lara, Taly, Amy, Olie and Mao. They forgot their true names, so they can't find the way to back home. Turtles decided to get back their name from Nayichu for them.
