Best early-game tame ever. Despite not having stances on mobile, it can still get a ton of berries, thatch and wood, the way its plates are shaped can prevent you from getting knocked off by stuff like kapros, raptors, etc. Whenever I need thatch, I hop on my stego. They are powerful too, and can fend off threats I usually couldn't alone. Only downside is they are a bit slow, and I wouldn't recommend for traveling.
