The Animal Amulets are amulets used by few of the members of the Noctambules-masques, such as the PJ Masks. When worn, they have the ability to remotely transform the user's regular pajamas (containing their linked-in powers) to super pajamas.
It is unexplained how users are able to obtain the Animal Amulets, and where they originated from.
Animal Amulets are not popular towards most Noctambules-masques, as they often rely on their Animal Totems as the independent source to transform their pajamas.
However, Les Pyjamasques' totem had got some direct inspiration from the functioning features of the Animal Amulets.
The appearance of the Animal Amulets may have been inspired from the Spider Bracelet from Supaidāman, a television adaptation of the Spider-Man comics.
The functionality of the Animal Amulets' is also similar to how Iron Man summons his armor when needed.
