Stereotypically speaking, fathers are either the most distant from their kids (workaholics, etc) or relate the closest, being a kid at heart (and probably a little stupid). I dislike both of those. Nidorino's typically busy and seemingly distant but he really means well. He cares about his kids and wants to be close to them. But he's not ignorant to what his kids like (even if they are all under 7), so he plays with them accordingly. Afterall, he was a free spirit once. What a loving dad, that Nidorino.
