The Lost Episode! is the thirteenth episode of Blue's Clues from Season 2. It was the thirty-third episode to be produced and the thirty-fourth to air.
This was the twelfth episode to use the usual "No, it's a clue!" line from Adventures in Art.
Steve cleaned up the paw print with the feather duster from "What Time Is It for Blue?", which he found while looking for the puppet he made for Blue and later lost in his back pocket.
When Steve went over to Shovel and Pail, he pretends to be an airplane just like he did in "Pretend Time" because Pail lost her toy airplane.
Also, the music playing when Shovel and Pail were playing with their toy cars is the same as the one for the vegetable cars from "Magenta Comes Over"
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.
Goofs
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.
