Different Tails?

Hi jammers! Me and Dolphino found out something interesting...

Check out Sizzlerat's tail. I know its the same thing it always has but...

look closer. now check out the new tails. (Lovelost made a animal like sizzlerat, I don't know why its saying she's a nm its happened before.)

Ok. Look at the new tail. this side <------

Now look at Sizzlerat's tail. There's something different about them, see?

The new tail has lines through it! Old one doesn't!
