Cooler

Cooler is the biggest flat Stamina boost in the Store: +50 maximum Stamina, paid for with a 5% cut to movement speed. A 1-star Toon goes from a 100-point bar to 150 (50% more) and a 5-star Toon from 200 to 250. Since running burns 10 Stamina per second, those 50 points are 5 extra seconds of sprint. The speed penalty is small in numbers: a 5-star Toon drops from 20 walk and 30 run to 19 and 28.5.

The natural owners are the 1-star Stamina Toons, Gigi, Waxwell, Yatta, Shrimpo, Gourdy and Soulvester, who start with the smallest bar. Waxwell stands out because his 5 stars of Movement Speed absorb the penalty best. The wiki also works out an extreme stack, with Friendship Bracelet, cards and the Dyle's Floor reward, that reaches 496 maximum Stamina.

The price is the steepest of any Stamina Trinket: 2250 Ichor, 250,000 meters traveled, and 30 Rare or higher items picked up (buying them in Dandy's Elevator Shop counts too). It was first added as Water Cooler on September 28, 2024 and came back as Cooler on July 3, 2025. It is on sale today.
