LEGO minifigures compatible double sized hand
The thief villain Jack has wounded the policeman Jeff.
Luckily Jeff was rescued by Dr. Alessio, who is a mad scientist who likes to help the toys in difficulty.
After a long and difficult surgery, Jeff received a prosthesis, a special big hand, with this he can firmly hold a big gun and enforce the law again :)
Ps: Jeff now also has a big hammer hand, to be used in difficult situations
