The VHS for this film came with an infomercial to receive donations needed to relocate the star orca, Keiko, back to the ocean. It included interviews from the stars of the film, the owners of the Oregon Coast Aquarium, and information on the "Free Willy Keiko Adoption Kit" which came with a Free Willy poster, stickers, a newsletter containing information on how Keiko was being rehabilitated, and a replica of the necklace that Jesse wears in this film. The kit only cost $24.99, and many people all over the world had donated. Soon after rehabilitation, Keiko was freed in the same area in Norway where he was assumed to first be captured. Keiko eventually lived to be 29 years old, making him the second oldest orca to have lived in captivity. The kit has since returned for sale in 2014 on http://savedolphins.eii.org except it now contains information on freeing orcas and dolphins worldwide instead of news about Keiko.
