Is this "normal"?

[marblesab]

Ok, I got a snail a new snail and I noticed that it came with two little hitch hikers. Now I've learned that not all hitch hikers are good, so I thought I would post here and see if they are something I should attempt to remove, or if I should just leave them as they are.

Yes, they are both alive.


....So, what do you think?
