Tamasan is a character that appears in Kirby's Dream Land 3. Tamasan appears in the third level of Cloudy Park. Tamasan wants Kirby to play a mini-game where Gordos of different colors slide out from behind a wall, and the number of Gordos of a certain color must be chosen. If Kirby gets it right 3 times, Kirby will be rewarded with a Heart Star at the end of the level.
Tamasan has a yellow ball for a head, and a blue and red ball for a body, somewhat resembling a molecule.
In Japanese, "tama" means sphere while "san" means 3. This refers to how its body is made of 3 spheres.
