Allie Ducks are found in Allie levels. A total of three appear in each level.
A player is not required to collect any Allie Ducks in order to move onto the next level, however, a certain number of Swampy Ducks are required to unlock future Gates in the various Locations. Allie Ducks count toward this total.
Allie Ducks require five drops of Steam to be collected. All other Fluids, except Water will kill the duck.
While in the Avoid It! challenge mode, the player must avoid all Allie Ducks and complete the challenge. If one is collected, the Challenge is failed and any succeeding challenges on the same level will remain locked. Note that if a duck is partially filled, the challenge will continue.
While in the Driller challenge mode, the player may have to avoid all Allie Ducks. If applicable, the same rules from Avoid It! are applied in Driller.
While in the Melody challenge mode, all three Allie Ducks are replaced with five musical notes. The notes accept and reject the same fluids as Allie Ducks but also have to be collected in the correct order.
While in the Duck Swap challenge mode, all three Allie Ducks are replaced with either Swampy Ducks or Cranky Ducks. The level is layed out the same except with those duck changes.
While in the Duck Rush challenge mode, six Allie Ducks are present instead of the customary three. The appearance and fluid acceptance is the same.
Appearance
While full, Allie Ducks have a lavender colour with an orange beak, white eyes, and a medium purple eye shadow.

Trivia
Allie Ducks are blue (when full), which represents serenity (calmness or peace), just like Allie herself.
Some elements of Allie can be seen visibly on the duck, such as the purple eyeshadow and the two eyelashes.
