A tiny toy dump truck, no assembly required. Captive wheels and dump box. The picture shows the series of intermediate designs. The wheels will most likely need to be broken free (just grab both sides of a single axis and twist) and some manual cleanup around the axle holding the dump box to the body will most likely be necessary.
