Critter Shampoo

Critter Shampoo is an accessory equipped in a social accessory slot that changes the color of summoned minions when paired with a dye in the corresponding dye slot. It is purchased from the Zoologist for each.

Trivia

 * The bottle seems to depict a Bunny similar to the Guide to Critter Companionship, another item sold by the Zoologist.
 * Sentries, The Stardust Guardian, and The Forbidden Sign can't be dyed with the Critter Shampoo. Instead, The Stardust Guardian and The Forbidden Sign can be dyed by dying the chestplate of the armor, while the Sentries can't be dyed at all.
