Snowball (1995)

A young boy and an old man team up to free a giant white dolphin from the swimming pool of a ruthless, one-legged millionaire Marcov in this upbeat Italian children's movie. Mischievous Snowball (the dolphin) gets into trouble when escapes into the beautiful Greek sea and playfully ends up swallowing the record of pension payments owed to Billy Bolla, an aged cruise ship entertainer. If the performer cannot quickly catch Snowball and induce him to produce the papers, he will have no retirement. He encounters ingenious Theo, the son of Marcov's maid. Theo adores Snowball and wants to free him. He befriends Billy and together they devise a clever plan involving a bus filled with water. ~
