White dot on tail?

[Shawn91]

As i was watching my axie eat, I noticed something weird on its tail. It looks like a white dot and I can't recall having seen it there before? Is this something I should worry about? She's still eating and stuff...and just as lazy as when i bought her...so I can't really say that it's bothering her. Hopefully the dot is nothing harmful...

Any advice on what I should do?

would help if you could post a pic so we could see exactly what it looks like.
