Annie Angel's Mermaid (Resource) Pack makes some small changes by adding pink hearts instead of red, kelp as the hunger bar, seashells as the armor bar, bubbles as the xp bar, sea foam green hearts for animal hearts when riding and some cute aquatic designs to the inventory GUI, crafting table GUI and furnace GUI.
