  • This episode would be recalled in "I'm So Happy!", when Shovel told Joe that he used to be afraid of dinosaurs, but is now interested in them.
  • The third pawprint changed to three different colors. It changed from blue to green, to red, to orange, and back to blue again before repeating. this resulted in Steve using three colored crayons: he started with a green crayon to draw the first color, then used a red crayon for the 2nd color and then an orange crayon for the third one.
    • When Steve was trying to put the clues together, the third color was yellow.
  • In the intro, Steve or Blue didn't appear, which made it a complete instrumental version.
  • As Steve opens his notebook, throughout the episode, he gets a surprise (in this episode, it roars like a dinosaur). This also happened in Blue's Big Costume Party.
    • It was called a "Dino-Notebook".
  • Turquoise appeared on a call reminder on the cork board.
  • This is the fifth and last of five episodes in a row where the first clue was found in the living room.
  • This episode was aired on the day of the 2000 US Presidential Election which George W. Bush won the election.


  • When Blue left the third clue on the ground, it was near the footprints that were found in the backyard at the beginning of the episode and the clue is no where to be seen near the footprints in the present day. Either this proves that clues can wear off of their own after Blue leaves them.
    • The clue also disappeared after Steve wrote it down in the notebook.
