The red hearts will restore 10 hearts, the yellow 20 hearts, and the green 30 hearts. Crainer did that once to SSundee in Crundee Craft. They can be eaten to restore health as of 1.5.4. Chapter 157: First word - Crundee Chapter Text 'Come on sweetie, say mama' Crainer cooed out as he was looking down at his one year old daughter. Yellow hearts can also be crafted down to red. The Hearts are used to craft the different levels of Heart Canisters. They are not obtainable through normal survival.
