On Mobile, Easy gamemode: I fought it because I had to (it was near my base) and all you really need if on land is a tame with good health to tank damage (like a higher leveled carbonemys).

(This wasn't actually the case for me, because I had to sacrifice some of my lower leveled tames like my moschops and one of my dodoes, but then again, I wasn't expecting it to spawn all of a sudden.)
