This is the second time when a character outside the PAW Patrol goes down the Lookout Slide, his or her name is shouted by the background voices (that being the Alien), the first being "Pups Go All Monkey" when that character is Mandy and the third being "Pups Save a Flying Frog" when it is Smiley. Of course, at the time the alien goes down the slide, so does Ryder, but his name is not shouted, another second time, this one being when someone who goes down the slide, his name is not said, the first being "Pups Save Alex" (that someone being Alex).
This is the first episode with Chase's "Super Spy" uniform. His pup pack was also upgraded with a zipline.
Towards the end of the episode, Ryder slides down the Lookout's slide for the first time in the series.
Chase wears boots for the first time, to go along with his Super Spy uniform.
Also, Chase is the first pup to ever wear any kind of footwear.
Chase's new Super Spy gear appears to be a reference to both SWAT (due to their use of specialized gear) and Covert Special Forces like the Navy SEALS (know to have specially trained dogs for covert military operations and high tech gear).
This is the second time Mayor Goodway wears her Cowgirl hat and seen with her washtub bass, which first appeared in Pups Save a Hoedown. It is also revealed that she is a good friends with Farmer Yumi, as she is leaving Farmer Yumi's farmhouse after a hoedown.
