Update: Right after I wrote my last post, I turned off the music. I watched Ricky and Sticky for a little bit without the music. Almost as soon as I turned off the music, they stopped moving: antennas, everything. I turned "You and Me Together" on again at 7:27 and watched them closely. Both cockroaches started moving their antennas again! When the music stopped, they stopped! THIS IS CRAZY COOL!
