The purlovia actually is very useful with taming creatures... at least on mobile, creatures will aggro on it while it’s underground, yet it will take no damage, serving as a “bait” for most aggressive creatures, set the purlovia on passive so you don’t attack the things you wish to tame. Simply build a big taming pen in the arctic, put the purlovia in the pen, make it dig, wait for the rexes, sabers, wolves, and even possible gigas to aggro on the badger dog, open the gates, close them, tranq out the creatures while they are distracted, and enjoy your new OP tames!!!
You can use them as a hidden treasure chest. If you are a solo player this is very helpful, as long as you remember where they are. Also if someone knows where it is, they cant shoot it, and they have to waste nades or c4
