On peu remarquer les similitudes entre les poses de Banjo et du petit ours, de plus le jeu parle du sorcière nommée Brentilda bizarre !:

You can see that the two bears have the same behaviour : running, looking for something and an object under their arm, chasing by a monster. In Cristal Castle, we heard a witch nammed Bretilda... Weird !
