Baby Bear (cameo in living room picture, based on her original incarnation)
Josh, Blue, Tickety, Slippery, and the viewers become the Thinking Squad, a group of superheroes who use their brains to figure out problems. When they hear a mysterious noise, they play Blue's Clues and use their skills to figure out where the sound is coming from.
The full episode is available on the NickJrPlay YouTube channel. Watching the video needs payment or a subscription.
This is the first episode to be a remake of a season 4 episode.
Aside from Super Blue, everyone else's superhero outfits are different.
Song Man simply wears a red cape without a mask.
Though in some Halloween promos and bumpers for Nick Jr. on October 2019, he also wore a matching mask and gloves.
Clock Girl has a brighter purple cape with white stars on it and lacked the bands on her bells.
Super Soap's armbands and belt are blue, the yellow star on his belt has rounder points with a light green outline, the yellow lightning bolts on his armbands are replaced with light green dots, his lightning bolt antennae are held by blue rods instead of springs, and his sponge wand has a light green handle with a rounder-pointed sponge star.
Wonder Drawer has a light blue cape with a yellow edge; a yellow headband with a red outline, Josh's notebook in the middle, pale yellow stars with red outlines on the ends, and blue lines in between the stars and notebook; and a light blue mask with a yellow outline (all of which are sparkly).
Wonder Drawer also had her outfit on for the rest of the original episode, while in this episode she only had it on while Josh/Song Man got the Super Duper Notebook.
At the beginning of this episode, Josh/Song Man needed help calling for his guitar. In the original episode, Steve/Stripe Man needed help finding his mask.
The Thinking Squad followed the sound to the living room in the original episode, while they stayed in the bedroom in this episode.
The Super Duper Notebook has a red cape, while in the original it had no cape.
Josh/Song Man teaches how to draw the clues in song, while Steve/Stripe Man doesn't.
Josh/Song Man goes to the left and the bubbles with the paw print is seen out the window. In the original, Steve/Stripe Man goes to the right.
The scene with Paprika and her teddy bear aren't in this episode.
Josh/Song Man sings the last "MAIL!" like he usually does. In the original, Steve/Stripe Man announced heroically that "The mail's here" instead.
The hero in the original video letter was Super Morgan, who helps people out. The super hero in this video letter is the Super Doodler, who can doodle really fast.
The heroes of Super Hero Ville have regular skin and hair colors and wear different outfits.
The silhouette of a flying adult superhero is replaced by a generic superhero boy.
In the original episode, the clothes that were the 3rd clue were in the bedroom and Blue/Super Blue put her paw print in them. In this episode, they looked different, were in the living room, and already had a paw print on them.
The area where the washing machine was located to the left of the kitchen in the original, while in the remake it was located to the right of the bedroom.
Frank/The Cheerer-Upper doesn't join the others in following the sound to the washing machine.
