If yo encounter a trike with a glowing effect around it’s horns, you may want to turn around. The glowing effect is the result of a large predator and powerful predator(spinos are a key example) being nearby, which can save you, your tames, and your stuff.
Fun tip: A sarco, lvl 10, 70, 4, doesnt matter- is the same strength as a same lvl one. Both with full health, they will hit each other, and they both deal the final blow, killing them both. Saw this on a server, 1 trike vs 1 sarco, both died without any outside intervention.
