Pups Save the Space Alien Trivia
- One new character debuted in this episode:
- This is the first Season 2 episode that aired, but was shown out of sequence, as "Pups Save the Penguins" and "Pups Save a Dolphin Pup" were the actual first episodes of Season 2, production-wise.
- 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 second 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.
- 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.
- In the title card, Chase is shown in his regular police uniform, but in the episode, he's in his super spy gear.
- Chase's pup-pack disappears and reappears several times in this episode.
- This seems to be a recurring error in several episodes of Season 2 where Chase is in his super spy gear.
