Dodos

These birds can be found in the jungle (or maybe mushroom islands, because of the lack of predators), they are passive and will be hunted by Wolfs, Cats and Ocelots. they can be bred with seeds and if you feed it a fruit (for example, apples!) they will in exchange, start digging for items with his huge beak, they will normally find leather, feathers and strings (items will be different depending on the biome) but will rarely find items like emeralds, name tags and even dodo beaks, that can be used to craft a powerful shears that can break hard blocks and will drop more items when breaking things like grass or shearing Sheeps!
