Before episode: Tiffi asks the Dutch Girl the item she is looking for. She replies that she has lost her wafer and says if she cannot find it she will eat the windmill, in which the windmill frowns. After episode:
Tiffi uses a metal (or, in this case, wafer) detector to find the wafer and the Dutch Girl does not worry about eating the windmill, and the windmill smiles.
Wafer Windmill is a somewhat hard episode. It has five somewhat hard - hard levels: 591, 593, 594, 595 and 596. It also contains level 600, the first level in which a dispenser dispenses three types of things. Overall, this episode is easier than the previous episode, Gummy Gardens.
This episode breaks the trend of every level containing conveyor belts as levels 591 and 604 don't have any.
There are five 4-coloured levels in this episode, which is more than most episodes.
This is the first episode since Crunchy Castle, which is 25 episodes earlier, that ends with a 4-coloured level.
This is also the 4th episode in the game to end with a 4-colour level, the first three being Cupcake Circus, Caramel Cove, and Crunchy Castle, all 3 having words starting with one letter and close to each other (episodes 13, 14, and 16 respectively)
This episode contains the fourth string of more than two ingredients levels.
This is the first episode in the whole entire game to have 3 straight consecutive ingredient levels in this episode 600, 601 and 602, the second episode is Toffee Tower, and the third episode is Chewy Citadel.
The end of the story has an error: It says "Thank's a lot" when it should say "Thanks a lot".
This episode contains level 594, a level that formerly resembled a windmill. However, it was redesigned, because others may think it resembles a swastika.
When this episode was released on mobile devices, the level numbers get wider and much clearer. This made the game more attractive on mobile devices.
This episode starts the trend of levels that end in 0 are not Jelly levels.
This episode would most likely take place in the Netherlands.
The background on mobile devices show Tiffi using the wafer detector and the Dutch girl is happy.
The release date of this episode is close to "World Day Against Child Labour".
