Pups Save a Mer-Pup Trivia
- Zuma, Skye, and Rocky are turned into mer-pups by touching noses with the existing mer-pups.
- Zuma, Skye, and Rocky become regular pups again once the moon is no longer seen over the horizon.
- This is the first episode to feature a title card with more than one pup on it (Zuma and Skye). As well, they are shown in their mer-pup forms as opposed to their usual pictures.
- This is the first episode in which Ryder specifically calls on a character that is not a pup during his briefing (Cap'n Turbot).
- The whale that waved to Cap'n Turbot may have been the baby whale that played with the diving bell in "Pups Save the Diving Bell".
- A flashback of a younger Cap'n Turbot was shown.
- Even though Ryder's new voice actor was featured in a previous episode, this is officially the last episode to use Owen Mason.
- Ryder gives his mission orders on the beach for the first time.
- The "sleeping bag wiggling" gag was used for the 3rd time.

- This is the final episode to use John Campbell as the voice of Ryder in the UK version.
- After Cap'n Turbot told the pups about his first encounter with mer-pups, Chase looked away and remarked, as if he was talking to the audience. This is another possible instance of fourth wall breaking.
- Ryder is able to fit and operate a pup's vehicle (Zuma's hovercraft/submarine)
- The entire mission takes place underwater.
