Little Mewtwo babe is being introduced to Absol dad. I imagine in most cases Pokemon can be known to take in other species of Pokemon cubs, but it's usually mothers. Fathers can still be a bit protective and territorial. So Ninetails is taking it slow.
Also fluffy Mewtwo bab! I can't get over it.
Eventually he'll learn to stand on his two feet!
