This article is about darker swirling cookie. For lighter one, see Compelling Cookie.

The Impenetrable Cookie (大がんこ^?, lit.: "Giant-Stubborn") is one of the treasures in Pikmin 2, and can be found inside of a Puffy Blowhog on sublevel 7 of the Cavern of Chaos, in the Wistful Wild. It is actually a hard, possibly burnt chocolate cookie.

Notes

Olimar's journal

“As I grow older, I've observed that I am becoming crankier. Today, I flew off the handle over a trifling matter. I feel like such a fool... I must learn to control my cantankerous temper! I can't allow my bad attitude to erode teamwork on this vital mission.”

Sales pitch

“It is hard. Really hard. Too hard. So hard that you're not sure you can eat it, even though you must. This hard snack is infused with the essence of stubbornness, and you are powerless to resist it.”
