Pons are the most common collectible in A Hat in Time, and can be found almost everywhere. There are green and pink/red Pons. They may usually be found in treasure chests, vaults, and by beating up enemies. The main use of Pons is to buy new badges and certain acts. The Pons Hat Kid has collected respawn when she reenters an act, without decreasing her total Pon count.
An additional type of Pon is the Rift Pon. These can only be collected during Purple Time Rift missions, where they are used to get to the next level of Purple Rifts. Other than this, Rift Pons have no use.
