- This is a flashback of how Rubble joined the PAW Patrol.
- It is revealed that Rubble was a stray pup before he was discovered. Therefore, it is never explained how the members of the PAW Patrol can talk, but the other animals can't.
- Rubble says he's a tough pup. This could be a reference to T.U.F.F. Puppy.
- The Korean broadcast of Nickelodeon places this episode as the second half instead while "Pups Save a Walrus" serves as the first half.
- There could have been a pup who had Rubble's job in the past. This is because of two reasons:
- This episode shows that Rubble is the seventh member of the team. However, on his rig there's a 6 and the number 7 is on Zuma's hovercraft.
- 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.
