Lego Domo - Weightlifter
Ok, did a 2 second research job on the Domo figures made possible by Wikipedia.
Here's what I learned:
Domo-kun first appeared in short stop-motion sketches on December 22, 1998 to mark the 10th anniversary of NHK's satellite broadcasting. Domo, the main character, is described as "a strange creature that hatched from an egg," with a large mouth that is locked wide open.
As far as I can tell theses little figures are about the size of a minifigure at about 2" tall.
