"First, we tried cleaning the polluted river by hand. Every other day someone would kayak out to the habitat to remove garbage, but that was not enough. Trash appeared at random times and in large quantities. Sometimes we would remove every piece of trash in the morning and by the afternoon more had reappeared. Thus, the 'Trashbot' was created in our image and likeness. It swims daily in the river and collects the trash. The Trashbot is saddened by the mess, but enjoys having a purpose in life."
