The guitar melody on the "So Long Song" samples the starting of Roy Kim's "Only Then" song.
Josh happy cries and then meows like a cat when he sees the picture of Shovel & Pail. In the play-along app version on Noggin, Josh didn’t happy cry nor meow like a cat when he saw the picture of Shovel and Pail.
Josh does an impression of Elvis Presley in this episode, just like Steve and Kevin did in What Story Does Blue Want to Play?
The picture of Mr. Salt and Mrs. Pepper on which the paw print for the second clue was was an illustration. In the original episode, it was a photograph.
After Josh finds the second clue, it was Mailtime. In the original episode, after Steve plays the riddle game with a sky blue Felt Friend with a green semicircle body, it was Mailtime.
In the Noggin play-along app version, Josh’s pirate hat had an orange feather that Blue made for him, but in the TV version, Josh’s pirate hat didn’t have a feather at all.
After the So Long Song, when you turn up the volume real loud, you can hear Josh shushing at the viewer, then whispering “bye, thank you” very silently.
The riddle game with a Felt Friend scene was cut.
Freddy and Fifi make actual appearances on the red felt board reading a newspaper in this episode instead of appearing as drawings on the living room picture or on Blue's drawing, while the other Felt Friend didn't appear at all.
None of these Felt Friends appear at the end unlike the original.
In the original episode the chalkboard is black with only a yellow chalk stick being used. In this episode the chalk board is green and Josh used sticks of chalk in lilac, blue, and orange.
Sudsy appeared to Josh and Blue right after Josh erased the chalk wave. In the original episode, Steve and Blue waited a while after erasing the wave to meet him.
In the original episode, Sudsy was black with an orange chalk outline. In this episode it was green with an orange outline.
Due to Paprika already existing, Sage and Ginger were born instead.
