Just for cuteness. My FireRed trainer, Eve has a little Mew that she found and took care of, whom she named Little Bit. Little Bit became comfortable around Eve and the fact that Eve is very secluded in the mountains her family owns. (Her family is very rich as they design pokeballs, even make custom ones for trainers or others, and also mine for stones)
Because she's so comfortable, Little Bit gives birth to four little Mini-Mews.
I love Little Bit's eyes, so pretty...
