Hamster

He's a silly, clumsy, childish hamster who doesn't know he's small.

For him, it's a normal size

He's silly and childish; if he feels an emotion, he exaggerates it greatly. For example, if he's happy, he'll be VERY happy; if you make him angry, he'll get VERY angry. But he's easy to calm down with sweets, especially colorful lollipops.

He likes having his tummy stroked, but you have to do it with your finger; you can't do it with your hand because of its size.

It's very fluffy
It is white
She has super tiny hands
I don't think he has ears... but somehow he hears, he's never even questioned it.

He eats nothing but sweets.
She will refuse any food that isn't sweet.

She throws a lot of tantrums if she doesn't get what she wants.
