What must Pokemon catch in the early stage of diamond?

Pokemon must catch fat birds, rosebuds, round sharks and so on in the early stage of diamond.

Pokemon diamonds can catch fat birds at first, and then they can catch rosebuds. After completing the Caodao Pavilion, you can catch the round-land shark in the bicycle lane cave, drop the clown fish in the misty place of Dianyuan Mountain, add the main pet to Lucario's egg given by the brave man of the steel island waveguide, and recommend the fire owner according to the above formation.

The first choice of "package"

Playing the treasure dream game, it is natural to choose one of the three. In Bao: Crystal Diamond/Bright Pearl, Turtwig, Little Fire Monkey and are three. Personally, I suggest to choose the little flame monkey, because there are fewer elves with fire attributes in this generation of works, and choosing him can make up for the fire damage. In addition, the little flame monkey evolved into Monferno, which is very powerful and suitable for most occasions.
