Ever hear of the tried and true dodo alarm? No? For this simple yet effective raid alert only requires one dodo (but you can use more). All have to do is set a dodo to aggressive and if anyone attacks a member of your tribe or one of your dinos the dodo will freak out and warn you of the intrusion!
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 easy tamed for beginners, and sometimes even good tames for more advanced people, you can breed bigger dodos so you can equip special items on them (dodo cultivator) and ride them, they eat berries and they need to be well protected because they are quite weak and slow
