Donna

Doh, doh, nuts, nuts! Donuts, donuts!

Donna (ドナドナ) is a donut-headed person who Tibby encounters in Rhythm Heaven Megamix. Donna is the guardian of Donut Land and the Donut Tower.

Personality
Donna is most notable for being hyperactive and obsessed with doughnuts. However, it is not the taste she loves, but instead their appearance, as evident by her objection to Tibby wanting to eat some and her wishes of meeting handsome doughnuts. She also likes to make many doughnut related puns.

Role
After being let down by Shep's lack of culinary skills, Tibby is left with an empty stomach and a desire for food. He arrives in Donut Land, and is immediately greeted by Donna, who makes many doughnut related puns at him. She asks if he likes doughnuts, which he admits he does (as in eating them), but she mistakes him for being a fellow doughnut enthusiast who admires their "handsome" qualities. She notes that the doughnuts have disappeared, and believes it is because she has not proclaimed her love enough for them to notice. Tibby instead suggests a lack of "Flow", causing her to task him with restoring it.

As he completes rhythm games, more doughnuts appear. Tibby is disappointed he isn't able to eat any, especially with his hunger, due to Donna's objections. After he completes all four rhythm games, "Flow" is completely restored to Donut Land, and Donna allows him to proceed as thanks.

It is later revealed she is the guardian of Donut Tower. Like the other guardians, upon completion of the tower's Remix, she sends the tower's energy to the Power of Rainbow.
