Lyle, Lyle Crocodile is a children's book written by Bernard Waber first published in 1965. It is the sequel to The House on East 88th Street, published in 1962.
The book is the second in the Lyle the Crocodile series. The fictional series follows the life of Lyle, a city-dwelling crocodile who lives in a Victorian brownstone with a family named the Primms.
The story begins with Lyle and Mrs. Primms going shopping and running into their neighbor, Mr. Grumps. The grouchy Mr. Grumps finds Lyle a nuisance because Lyle scares his cat, Loretta, and he has him thrown in the zoo. When Lyle is freed by his old performing partner Mr. Valenti, they go back to the house on 88th Street, where they find Mr. Grumps' house on fire. Lyle rescues Mr. Grumps, is declared a hero, and thus is allowed to stay with the Primms.
The musical film for Lyle, Lyle Crocodile was released for television on November 12, 1987. It made its first home video release by Hi-Tops Video (now Media Home Entertainment, Inc.) two years later.
The book was used in Jerry Spinelli's book Maniac Magee, where it is the favorite story of Hester and Lester, the younger children of the Beale family from the East End.
The book also appears on the U.S. TV series The Newsroom. In the second-season episode "Unintended Consequences," written by series creator Aaron Sorkin, producer Maggie Jordan (portrayed by Alison Pill) reads the story many times to Daniel, a young Ugandan boy (portrayed by Demoze Talbot) in a remote orphanage while on assignment.
