Hello guy that play mobile and can't find allos! I'm Spi/spiritbird8960 and I live near the hidden lake area just south of the carni island, and let me tell yah. I know where to find LOTS of allos. So, you can find them In the gourge about idk...east? Of the hidden lake, about around the foot of the mountain of Griffin mountain. You can also find them around the penguin/oil iceberg in north, on the sandy beach, as well as in the cold area around there. They are everywhere. You can also find tons on the carni island. Hope this helps!
