If you are talking about how to see how happy it is you have to have the poketch app Friendship checker which you can get from a girl in the Eterna city Pokemon center if you haven't gotten it already. The app looks like a page with Pokemon walking around and then if you hold the styler onto one of the Pokemon hearts will appear or not depending on how happy it is. There can be no heart, 1 heart, 2 hearts, or 2 big hearts.
The Pokemon Bronzor evolves due to level, and so affection doesn't have to be high, and he doesn't have to be holding anything. (Technically it is an "it," not a he, since Bronzor is genderless.) Bronzor evolves into the Pokemon called Bronzong at level 33. It remains a Steel-Psychic type after it evolves.
level 50 and level 100 are the best level's to see IV's.
A Hippopotas evolves at Level 34 in Pokémon Platinum. If you want a website to see what level Pokemon evolve, try Serebii.net

Try Neoseeker.com. I installed their Modifier but I have never got the chance to try the Pokemon level section. Try it and see if it is real for me though and see what happens, okay? good!
