Woolen (うーるん Ūrun?) is a recurring character in the Bust-A-Move series. She first appeared in Bust-A-Move 2 as a non-playable character, and has since gone on to appear in numerous other entries in the series.
Woolen is a pink-wooled girl with sheep-like characteristics. Her hair is pink, and she has two large horns affixed to her head. Her torso is covered in wool, and she wears a bell around her neck. In Bust-A-Move 4 onwards, she is depicted with hooves, while in Bust-A-Move 2 she appears to have normal human feet.
Woolen is shown to be very cheerful and playful. She is one of Bub's close friends. In Bust-A-Move 2, she is shown to be slightly flirtatious at times, playfully winking at Bub at the beginning of her match in single player mode. Judging from her room in Bust-A-Move 4, it can be assumed that one of Woolen's hobbies includes knitting as she has barrels and baskets of wool with knitting needles sticking out.
Woolen can curl up and envelop herself in a ball of wool. She can also send out a heart-shape wave at her enemies.
Woolen is the third opponent in the Story Mode of Bust-A-Move 2. She is fought in a field area.
Woolen has a small cameo in Bust-A-Move 3 in the background of Priccio's stage.
Woolen is a playable character in Super Puzzle Bobble. If selected, she runs up to Bub as he was about to leave with Chack'n to stop the Time Eaters, wanting to play.
