Well, i did a small google search for “Lepricon” after viewing timofey_tkachev’s cute old man MOC, and here comes the answer:
“A leprechaun (Irish: leipreachán/ luchorpán) is a type of fairy of the Aos Sí in Irish folklore. They are usually depicted as little bearded men, wearing a coat and hat, who partake in mischief.”
Remark: the actual spelling should be Leprechaun but Lepricon is the original title of the MOC.
Now let’s have a closer look on timofey’s build, what says ya? Perhaps a real 3D cartoon build is more precise to describe this amazing MOC!
