Soulful Artist Series

The Soulful Artist Series is a series listed in the Treasure Catalog in. It consists of nine treasures, all of which are tubes of paint with colors corresponding to the nine Pikmin types. All the treasures in this series are worth, and an extra is given when the entire series has been collected.

Each tube of paint refers to a different Pikmin type in multiple ways:
 * They share the same color as the corresponding Pikmin type.
 * They are typically found in the general area most players would first discover the corresponding Pikmin of that type.
 * The Uniquely You Goo and Neon Goo are the exception, since they are not found alongside Red Pikmin and Glow Pikmin respectively, and are only seen near the end of the game, in the Cavern for a King. The Uniquely You Goo is found in a sublevel with several red enemies, however.
 * Olimar's notes on the treasures typically compare them and the Pikmin.
 * The amount of usage they have reflects how long the corresponding Pikmin type has been in the franchise for.
 * Glow Pikmin appear much later in promotional material for Pikmin 4 as well as much later in the story, which could both contribute to the Neon Goo being the only one entirely unused.

In addition, the order in which they are laid out in the Soulful Artist Series also reflects when the respective Pikmin type is first found chronologically, with the exception of the Decorative Goo, which is listed before the Illumination Goo despite Blue Pikmin not being found before Yellow Pikmin.
