Answer:
The format is a bit confusing but the pen would go to the writer.
Explanation:
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.
The word dreaming in the sentence, “The children went to
sleep dreaming of the party“ is a participle.
To add, <span>a </span>participle<span> <span>is a form of a verb that is used in a sentence
to modify a noun, noun phrase, verb, or verb phrase, and plays a role similar
to an adjective or adverb.</span></span>
