In 2013, around the launch of Disney Infinity, Disney merchandise artist Jim Valeri posted a set of images to his portfolio of angular figures, resembling the character models from Disney Infinity, of Muppets Kermit, Gonzo, Miss Piggy, Animal, Beaker, and Fozzie Bear, mentioning that they were made a year ago and he had no clue what they were for or if they would be released. While not explicitly stated, it seems heavily likely from the timing and aesthetic that these were intended as characters for Disney Infinity who never saw the light of day, possibly due to the financial failure of the 2014 film Muppets Most Wanted.

There is an unused model of Dr. Heinz Doofensmirtz found in the game's data, suggesting that he was either intended to be playable or appear as a boss in a scrapped Phineas & Ferb playset.

Buzz Lightyear's Arch Nemesis, Emperor Zurg (who also appeared in Toy Story 2) was originally planned to be included as a playable character in the game, but according to John Vignocchi, the idea was scrapped because of his status as the Final Boss in the Toy Story in Space Playset.

There was originally going to be a Set Piece based on the set of ABC's "Good Morning America" show, which appeared in a demo at San Diego Comic Con 2013 before being scrapped for unknown reasons.
