Mr. Trolley is the father of Pickle Rick, and he is one of the most dangerous creatures in existance. His armored shell is impurvious to bullets and RPGs, and he is capable of flight for a limited time. He will stop at nothing to kill his intended target, sometimes reaching speeds up to 100 mph. Usually, one round of artillery can destroy him, or at least, slow him down. The only way to contain him is to trap him in a room with walls made of any sturdy material with doors that are only slightly taller than a human.
