Is it necessary for the little yellow duck to be promoted to the full level in the daily windy journey? Ducks have a strong magnetic force, which can suck away all the elves who pass through the Han Meimei checkpoint in two rows. Colorful wings can only be in one row. The magnetic effect of colorful wings is useless at all. I use the collection stream to equip the front of the castle, which is similar to the abuse of the wild stream. The little yellow duck is easy to explode.

Then the question is coming. Is it necessary for Little Yellow Duck to be promoted to full level? My bottle is just full. The little yellow duck can attract the surrounding elves and get extra points in the game. It is a very good pet. Its complete set of equipment is Newton Apple, which can also bring many collection points.

Although Little Yellow Duck and Han Meimei don't have combined skills, this pet's dual skills are very suitable for collecting genres. However, if you already have exclusive pets of various collection genres, there is really no need to upgrade the yellow duck. Just looking around.
