The Imperative Cookie (さいみんクッキー?, lit.: "Hypnotic Cookie") is a treasure in Pikmin 2. It is actually a cookie glazed with a cinnamon swirl. It is found on sublevel 2 of the Glutton's Kitchen and is sometimes found on a ledge. Breadbugs and other enemies may impede the Pikmin retrieving this treasure.
The exact location of this treasure changes each time the floor is loaded. The optimal way to collect it is either to retrieve it without any Breadbug interference, or by overpowering the Breadbug as it attempts to carry off the treasure. 8 strength is needed to accomplish this. Some treasure configurations render this impossible however. For consistency, it is highly recommended that the player enters the cave with a few Purple Pikmin, especially since you might need to overpower it using a Sheargrub's corpse, and this can only be done using Purple Pikmin. Once the Breadbug is defeated, their hole will disappear and all items and treasures it has taken will be dropped.
