- This is a flashback of how Rubble joined the PAW Patrol.
- It is revealed that Rubble was a stray pup before he was discovered.

- The Korean broadcast of Nickelodeon places this episode as the second half instead while "Pups Save a Walrus" serves as the first half.
- Apparently, Zuma has no spoken dialogue in this episode.
- There could have been a pup who had Rubble's job in the past. This is because of two reasons:

- Rubble's icon can be seen on the TV in the Lookout, although he was not yet a PAW Patrol member.
- When Rubble is snowboarding, he switches in and out of his vest.
