From Pikipedia, the Pikmin wiki
The Sweet Dreamer (娘のおやつ?, lit.: "Girl Snack") is a treasure in Pikmin 2. It is actually a doughnut glazed with strawberry icing, and a recolor of the Chocolate Cushion. It is found on the last (6) sublevel of the Glutton's Kitchen and is found somewhere in the area. It is subject to being taken away by Breadbugs and an even larger Giant Breadbug, so they must be dealt with if they gain possession of the item.
“I've toiled long and hard to collect all of these tasty treats. Surely it won't matter if I bring one back for my daughter as a souvenir. She loves snacks!”
“A comfy, not-too-sugary bed. Youngsters who sleep here will have the sweetest of dreams.”
