The Larry-Signal plays an important part in this film, as it signaled to LarryBoy that the Fib has assualted Bumblyburg.
The Larry-Signal is never seen, but mentioned, as Mayor Blueberry says to Larry, that he must contact Larry, since LarryBoy can't see the signal in the daytime.
The Larry-Signal only made its appearance in the music video, Rock On, LarryBoy.
- The Bat-Signal is an important part of Batman, in which the LarryBoy Film Series is based.
- In the Bumblyburg Science Lab, a button to activate the signal is on the wall in case an alien ever crash-landed there.
