In the scene where Skye approaches Chase and Ryder when they are discussing the song, Skye is seen wearing her vest. In the next scene, Skye is seen without her vest. After Ryder talks about the visitors, Skye is seen wearing her vest again.
At the entrance of the Lookout, only Marshall and Tracker wear their own vest. Once they are heading up, Chase, Rubble, and Everest wear their own vest before the change room scene.
When the band is about to perform, all the pups are wearing their vest. In the next different scenes, Skye and Zuma are seen without their vest.
This episode appears to establish that Tracker's Jeep is the only one of the pups' vehicles that does not convert into a pup house. However in the later episode, Pups Save Monkey-dinger, it can.
