We don't know if this is a bug or a glitch or part of the game where you can name your pet that long. The maximum length is 8 characters, and maybe right now you are scratching your head how others did it.
Let's assume you have already summoned your pet, click you pet and click Check and you will see your pet stats and skills. Click Update Name
After than, type "s " without the quote and a space.
Your pet new name is now
The Labyrith Forest is a maze divided into 16 foggy sections. There was once a legendary adventurer who said that the correct route to take was up, down, left, right, down, up, left, up, up, left... (@[email protected]) Sorry, I'm getting dizzy!
That name is probably a hint in the maze-like Labyrith Forest map.
