# Caretaking fees

To keep a Blobble happy you need to feed it, give it some love and give it something to drink.

You can do these once a day for free, or pay a small fee in bnUSD to keep your Blobble fed, happy and full of drink.

The bnUSD is used to mint BST and then all the BST is added to the [Blobble Treasury](https://university.blobble.xyz/game-play/blobble-treasury).
