Blue is a sad, lonely Brothers Bear residing in his own beach hut during the events of Donkey Kong Country 3: Dixie Kong's Double Trouble!.
In the events of the game when Dixie and Kiddy visit him, he says that he is sad because no one remembered his birthday and he got no presents because of it. Though, only Blizzard remembered about it, but he lived too far away to deliver his present to Blue.
Once the two monkeys speak to Blizzard for him and obtain the present, they must head back to Blue and give him the present. Oddly, the present is a Bowling Ball. Blue finds no need for it so the monkeys get to keep it. This Bowling Ball is later used to power up Bazooka's cannon in Mekanos so the two can reach a hidden Banana Bird Cave. Since then, he felt happier.
- His name is a take on his color and how he feels "blue".
- According to the calendar, his birthday is on January 16th. It can be seen if one looks closely, but only in the Super Nintendo Entertainment System version. This could possibly mean the event took place on the mentioned date.
- In the Game Boy Advance version, a happy birthday card from Diddy can be seen in the background if one looks closely.
