No, actually quite ON-topic... The second question is how did he/she get in there? Assuming that the plastic part was properly connected to the PEM, I would inspect the rest of the ducting for any added "ventilation holes", since I don't expect there is enough space for it to get around the blades in the blower.
To your first question, I would recommend immediate deportation back to its home country. Definitely an unwanted intruder.
