Churros

Churros is Sola's pet, and he never leaves her side. He is always seen with Sola, and they appear in the same games. (The Legend of Dark Witch (+Renovation) and The Legend of Dark Witch 2)

Appearance and Personality
Churros is a round yellow ball with wings. He floats and also has a curl on top of his head. He is always seen blushing.

Churros is sometimes seen as annoying, as he can only say "Puu!", leading to many bosses thinking he is loud and obnoxious. It seems only Sola can understand him. Generally, Churros serves no role in the overall plot.

The Legend of Dark Witch: Chronicle 2D Act (+Renovation)
Churros is not mentioned in The Legend of Dark Witch, but he is still by Sola's side throughout the game.

The Legend of Dark Witch Episode 2: The Price of Desire
Churros, while still not a major character, is mentioned by bosses in the game. He is also shown in the revenge attack "Churros Scramble!" in which multiple Churros attack enemies, meaning there are likely more species like Churros.
