(for ark mobile players, because console, switch and pc do not have this)
Breeding dodos is hard. Cult bit (gather veggies from normal bushes) can be put on a rideable dodo (size 2.4x and up) if they are 2.6x size or larger. 3.0x rideable dodos can equip the dodo deci bit (destroy any structure even tek), and dodos 3.4x and up can do a groundpound (swipe down, stuns nearby players and creatures, although makes them attack you after) Max size is 3.5x and dodos can sit on your shoulder if below 0.75x.
For the guy who said that it would be cool if a dodo could sit on your shoulder: on ark mobile, a dodo smaller than .75 can in fact be carried on your shoulder. Dodos over 2.6 can be ridden. Fun fact. :)
Dodos are good at helping you get an oviraptor. They produce dodo eggs, which oviraptors eat. You can kill the ones in the wild and harvest raw meat which oviraptors also eat. And remember, to tame and oviraptor first KO it, then feed it eggs and raw meat. Plz like!
