Ojamajo Doremi, also known as Magical DoReMi in most parts of the world, is a Japanese animated series created by Toei Animation. Spain had all seasons dubbed in Spanish, but even though all of Season 1, Sharp and a major part of Dokkan are easy to find, the third season, Motto, is very hard to find in that dub. Only 5 episodes have been found so far.
UPDATE: As of April 7th, 2020, somebody has uploaded the entire season here, therefore making the dub found: https://mega.nz/folder/WBU1GC4Y#nVaosk56qcQS5G_Ze0q6tw
