The only error I can see in this sentence is roll-a-coaster. I believe it should be a roller coaster instead, which is a ride in amusement parks. Other than that, it is more grammatically correct to say "I've just gotten off the wooden" rather than "I just got off the wooden" however, it's up to you.
I’m not understanding the question exactly
