On Virtual Pets
Mettotchi appears on every version as one of the six possible teens, evolving from any child with 6+ care mistakes and with 9 or less Happiness points. It is the worst care teen. Its adult evolution is determined from care, what it was fed, and what items were used. From the second generation onward, a user's My Tama raised under the same conditions may resemble it, but with a different body color and other traits inherited from its parents.
