This is third episode where viewers say "Notebook!" from "Mailbox's Birthday" was not used.
This is the first time the viewers interact with the video letter.
They would interact with the video letter again in "Joe's Clues".
The music for the "Go Back" song (specifically the version that played when everyone was looking for Blue's backpack) also played as a background music for several PC games like Blue's 123 Time Activities.
The children in the video letter said "Hi Steve and Blue" although Blue was not anywhere near the Thinking Chair around that time.
When the third clue is seen, the mast of a boom mic can be seen on the upper right corner.
After Steve drew the third clue on his notebook, the pawprint is still seen on the tree, but the size and color changed. However, this was fixed in the Kevin and Durate versions after Kevin and Duarte drew the clue.
The thump sound heard when Steve sits in the Thinking Chair was played late.
