This may be a reference to Foggy Bottom, the hometown of Mayor Humdinger on PAW Patrol, another show produced by Guru Studio.
The animation is slightly improved in this episode.
Cumulo is revealed to be female.
In this episode, her sides are smaller, and she also sounds slightly different.
The Wishing Tree sequence is very different from previous episodes. True levitates to a higher part of the tree to receive her three Wishes, and the Wishes now all state their names. Her vocals in this sequence have no reverb like in previous episodes.
True now says "Zoo, zip, zap, Wishes in my pack!" after receiving her Wishes.
Grizelda and Frookie do not appear despite being advertised in some promotional images for the special.
True and Glummy Glooma come up with a special day for Glummy Glooma called Glum Chums Day.
Purple rain falls near the end of the episode, to the liking of Glummy Glooma.
This could be a reference to the movie Purple Rain and Prince's song of the same name.
