- Going by production order, this is the fifteenth episode of the first season.
- This episode reveals Blaze, AJ, Gabby, the Monster Machines, Joe and Gus are all Truck Rangers.
- This is the first time Crusher encounters a skunk.
- This episode reveals that Blaze is an excellent guitar player and singer.
- It's also revealed that Crusher can play the accordion.
- This is the first time Stripes sings, as shown when he salutes and sings the Truck Rangers jingle.
- Stripes is the fifth Monster Machine other than Blaze to sing, after Darington, Crusher, Starla and Pickle.
- This is the third episode where Crusher steals something after Tool Duel and The Jungle Horn.
- Sound Wave Showdown is the first song that exceeds the usual 30-50 second length, as well as the first to last about a minute.
- It's also the first song to actually be sung onscreen by the characters, as songs are generally performed offscreen during montages.
- Blaze is revealed to have a measure of four meters long.
- The type of guitar that Blaze uses is a tenor electric, as despite having the appearance of a bass (having four knobs on the headstock instead of six), it sounds like a regular electric but in a mid-tone range.
- Whenever Gabby is about to arrive, the "Reveille" bugle call can be heard, which is a traditional call to wake up the members of a military facility at sunrise.
- When Blaze defeats the Robo-Bear during Sound Wave Showdown, it's a reference to the Dora the Explorer episode "Dora Saves the Crystal Kingdom", when Dora defeats the Greedy King.
- The Truck Rangers are a spoof of the Boy Scouts or Girl Scouts of America.
- The volume knob on Blaze's amplifier going up to eleven is a reference to the movie This Is Spinal Tap, where an amplifier has the same thing.
- When Blaze and Stripes enter the cave and they come to the first set of tunnels, Stripes' hat is gone.
- When Blaze and AJ raise the flag, the badges can be seen on the stage but later on, Gabby unveils them.
- In addition, while Blaze is transforming and when he starts his song to stop the Robo-Bear, the Super Bravery Badge can be seen on its post, even though it was stolen. In the next scene, the Robo-Bear is carrying it.
- The position of the badges on Blaze's hat and its orientation repeatedly change throughout the episode.
- In the opening scene, Stripes and Starla already have their respective badges on their hats even though they haven't earned them yet. The next time they're seen, they don't have them.
- When AJ says, "Try another one, Blaze!" he moves and the mountain climbing badge can be seen on his sash despite not earning it until later.
- When Gabby unveils the badges, a trapdoor opens on the stage to let them out, but when the robo-bear is about to steal the Super Bravery badge, the trapdoor is closed.
