Synopsis
After the Turtles discover a Kraang plot to turn Earth's water into Kraang water, they infiltrate an undersea Kraang base guarded by a sea creature from Dimension X. Shredder interrogates a captured Kraang droid and learns that April is not only an ally of the Turtles, but the key to the Kraang's ability to take over Earth, so Shredder sends Karai to capture her. April is skilled at evading Karai, but when cornered, she is terrible at fighting and is beaten up, but manages to escape by using a lesson that she learned from Splinter when Karai shows sympathy for her.
