This set is one of the many figures made for the "Extreme Grinch" line. Per the caption, this line was inspired by a subplot in the shooting script, nicknamed "Whovenile Delinquent Grinch", where Martha and the Mayor think back on their teenage years. In the subplot, the Grinch was a rockstar motorcyclist. That part of the script was cut, but these toys have survived. 

​

This figure comes with two roller skates, eight spare wheels, two spanners, 2 screws, and two nuts. As the packaging says, the grinch has a wire inside him, allowing you to pose his arms and legs.
