If you don't know what the rolly is yet, you haven't played far enough.
If you know what the rolly is, you know its frustrating. But I found a few things out about them that may help you.
1) If you super sprint into the rolly, sometimes you ragdoll, but most the time you will actually push it around. While you are pushing it, you are dealing damage to it, and it will eventually explode. (This may be an effect of Tornado, not sure)
2) Failing that, you can super sprint away from the rolly. It will go back into a ball to chase you. You can pick up the rolly while it is in a ball, so just pick it up and TK it away, which will either de-spawn it, or explode it.
