A Honey Jar is an item in Super Paper Mario.
This item is the Super Paper Mario replacement to Honey Syrup, an item in previous Paper Mario games that restored FP. This item, instead, gives Mario 10 HP as there is no FP stat in the game as it dropped some of the RPG elements from the first two.
Honey Jars can be obtained and used in many ways. The Honey Shroom item still exists as it is made by cooking both a Shroom Shake and this item. There are many items that can be created with this one such as the Honey Super and Honey Ultra items as well. By mixing the Honey Jar with a Mild Cocoa Bean, you'll obtain the Sweet Choco-bar item.
