  • Running Gag: The hotel manager's extremely acute sense of smell.
  • The title is misleading. Unless the episode was presented in 3D on Teletoon, the plot had nothing to do with 3D glasses.
    • However, it is explained as the room Johnny stays in is 3D. Most people misunderstand the title, however Johnny was wearing 3D glasses on the card, which does not make sense.
  • Missy, Sissy's dog, makes a cameo in this episode.


  • Johnny's parents saw Dukey talking.
  • The hotel manager did not noticed that Dukey was talking.
  • After the Johnny and Dukey image is erased, when the manager is on the wall, the image is still on the camera.


Hugh and Lila: Go to the beach!
Hotel Manager: I will find you flame headed boy and his dog!
Hugh and Lila: Where's the dog?
