The otter god and the jerboa king have sent their messages of warning in protection of their respective shoulder pets... So I too The Defender of the bulbdogs send mine! To any heartless survivors who would consume my brethren as a snack... Beware you heartless souls for you will be found and I as the defender of all bulbdogs shall kill you and use you as sustenance for the bulbdogs so that they can seek out and catch other bulbdog eaters! SOoo bulbdog devouring humans, think about that next time you tuck into the flesh of my glowing friends...
Before approaching a bulbdog, Make sure you have aquatic mushrooms. The amount varies between levels. All you have to do it out the mushroom into your inventory slot and approach the animal. Press Y ( On Xbox) to feed it. There should be a bar that shows its taming level. On a lystro if you walk to far from it, The taming restarts ( At least it did for me ) I am unsure if it is the same for bulbdogs. But better safe then sorry . . !!
Oh and also be careful there are nameless down there to the castle is hard to spot but just fly around green OB and look by it and just look for the top of the castle then by it there should be a hole by a lake
You can find these on vulgaro by this castle there’s a lake and there is a hole in the middle go in to the hole and there will be an abretten area go in to it and there will be ravagers and crabs and bulb dogs and shiny horns there is also a rock drake area but I don’t know if they spawn there
