The correct answer to the Tiny Novice Tic-Tocks quiz is only the “Tic-Tock” video is Legal in Tiny Novice.
The “Tic-Tock with Back” and “Tic-Tock Paper Dolls” videos are both Illegal in Tiny Novice due to being stunts. A stunt is:
Any skill in which a top person is supported above the performance surface by one or more persons.
During the Tic-Tock with Back the back is supporting the other athlete off the ground and during the Tic-Tock Paper Dolls each person tic-tocking is being supported off the ground as they switch legs.
The explanation is based on the 2017-18 version of the cheer rules dated August 30, 2017.
