Red Cheerleader Cookie

Red Cheerleader Cookie is an NPC Cookie that appears in Cheerleader Cookie's Island of Memories. She is a cheerleader for an opposing team, and acts as the boss of the Memories.

Though she is at first very harsh towards Cheerleader Cookie, after she is defeated in a cheer-off, she learns to respect her, and the two of them become friends.

Strategy
Red Cheerleader Cookie's boss fight is a rhythm game, without the rhythm. Try to pay attention more to the button and colors than the sounds, because the music and sound itself is more likely to throw players off than it is to actually help them succeed.

The final version of her boss fight is noted to be perhaps the hardest of all the bosses in Island of Memories, and may take several tries to nail down exactly how to do it. Keep in mind that all patterns repeat eventually, and try to memorize the longer ones to some degree, as they are the most dangerous to Cheerleader Cookie's health with the large number of misses that can be caused.

Trivia

 * Curiously, Red Cheerleader Cookie has many unused sprites, seemingly as though she was originally intended to be playable in some form, though there is no other evidence of this.
 * Red Cheerleader Cookie's boss fight may have been styled off of Taiko no Tatsujin, a popular series of rhythm games.
