Answer:
"it is some crazy alien adventure"
Step-by-step explanation:
The sentence "it is some crazy alien adventure" is presented in a very informal and relaxed way compared to the rest of the text which presents a more formal language. In this case, to keep the text completely harmonious and appropriate for the audience and the subject it addresses, it would be important that this sentence be revised and modified. It could be rewritten as "it is an abnormal alien adventure."
