Many companies made cuddly toys modeled from Knut. Steiff, a toy company, made Knut-based stuffed animals in three sizes and models: sitting, standing, and lying down. They all sold out at the Berlin Zoo in only four days. The money was used to improve the bear's home. Candy company Haribo sold a raspberry-flavored gummy bear sweet called Cuddly Knut beginning in April 2007. They promised to give ten cents to the zoo for every package of Knut sweets it sold. The gummy bears sold very quickly as well.
