Alisa the Cybunny and her sister Bea the Ixi went to the Money Tree one day, but found that the Brain Tree was in his place. Alisa stood up to the Brain Tree, who was refusing to give out donations without quests, saying that the Money Tree must have been on holiday. This made the Brain Tree angry and he scared everyone away.
